 Each set of stats only applies to the indicated device; if you want
 system-wide stats you'll have to find all the devices and sum them all up.

-Field  2 -- # of reads merged, field 6 -- # of writes merged
+Field  2 -- # of reads merged, field 6 -- # of writes merged (unsigned long)
     Reads and writes which are adjacent to each other may be merged for
     efficiency.  Thus two 4K reads may become one 8K read before it is
     ultimately handed to the disk, and so it will be counted (and queued)
     as only one I/O.  This field lets you know how often this was done.

+Field 10 -- # of milliseconds spent doing I/Os (unsigned int)
     This field increases so long as field 9 is nonzero.
 
     Since 5.0 this field counts jiffies when at least one request was
     started or completed. If request runs more than 2 jiffies then some
     I/O time will not be accounted unless there are other requests.
 
-Field 11 -- weighted # of milliseconds spent doing I/Os
+Field 11 -- weighted # of milliseconds spent doing I/Os (unsigned int)
     This field is incremented at each I/O start, I/O completion, I/O
     merge, or read of these stats by the number of I/Os in progress
     (field 9) times the number of milliseconds spent doing I/O since the
     last update of this field.  This can provide an easy measure of both
     I/O completion time and the backlog that may be accumulating.

+Remote coverage collection
+--------------------------
+
+With KCOV_ENABLE coverage is collected only for syscalls that are issued
+from the current process. With KCOV_REMOTE_ENABLE it's possible to collect
+coverage for arbitrary parts of the kernel code, provided that those parts
+are annotated with kcov_remote_start()/kcov_remote_stop().
+
+This allows to collect coverage from two types of kernel background
+threads: the global ones, that are spawned during kernel boot in a limited
+number of instances (e.g. one USB hub_event() worker thread is spawned per
+USB HCD); and the local ones, that are spawned when a user interacts with
+some kernel interface (e.g. vhost workers).
+
+To enable collecting coverage from a global background thread, a unique
+global handle must be assigned and passed to the corresponding
+kcov_remote_start() call. Then a userspace process can pass a list of such
+handles to the KCOV_REMOTE_ENABLE ioctl in the handles array field of the
+kcov_remote_arg struct. This will attach the used kcov device to the code
+sections, that are referenced by those handles.
+
+Since there might be many local background threads spawned from different
+userspace processes, we can't use a single global handle per annotation.
+Instead, the userspace process passes a non-zero handle through the
+common_handle field of the kcov_remote_arg struct. This common handle gets
+saved to the kcov_handle field in the current task_struct and needs to be
+passed to the newly spawned threads via custom annotations. Those threads
+should in turn be annotated with kcov_remote_start()/kcov_remote_stop().
+
+Internally kcov stores handles as u64 integers. The top byte of a handle
+is used to denote the id of a subsystem that this handle belongs to, and
+the lower 4 bytes are used to denote the id of a thread instance within
+that subsystem. A reserved value 0 is used as a subsystem id for common
+handles as they don't belong to a particular subsystem. The bytes 4-7 are
+currently reserved and must be zero. In the future the number of bytes
+used for the subsystem or handle ids might be increased.
+
+When a particular userspace proccess collects coverage by via a common
+handle, kcov will collect coverage for each code section that is annotated
+to use the common handle obtained as kcov_handle from the current
+task_struct. However non common handles allow to collect coverage
+selectively from different subsystems.

-Amlogic Meson8 and Meson8b SRAM for smp bringup:
-------------------------------------------------
-
-Amlogic's SMP-capable SoCs use part of the sram for the bringup of the cores.
-Once the core gets powered up it executes the code that is residing at a
-specific location.
-
-Therefore a reserved section sub-node has to be added to the mmio-sram
-declaration.
-
-Required sub-node properties:
-- compatible : depending on the SoC this should be one of:
-		"amlogic,meson8-smp-sram"
-		"amlogic,meson8b-smp-sram"
-
-The rest of the properties should follow the generic mmio-sram discription
-found in ../../misc/sram.txt
-
-Example:
-
-	sram: sram@d9000000 {
-		compatible = "mmio-sram";
-		reg = <0xd9000000 0x20000>;
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges = <0 0xd9000000 0x20000>;
-
-		smp-sram@1ff80 {
-			compatible = "amlogic,meson8b-smp-sram";
-			reg = <0x1ff80 0x8>;
-		};
-	};

-== Introduction==
-
-LLCC (Last Level Cache Controller) provides last level of cache memory in SOC,
-that can be shared by multiple clients. Clients here are different cores in the
-SOC, the idea is to minimize the local caches at the clients and migrate to
-common pool of memory. Cache memory is divided into partitions called slices
-which are assigned to clients. Clients can query the slice details, activate
-and deactivate them.
-
-Properties:
-- compatible:
-	Usage: required
-	Value type: <string>
-	Definition: must be "qcom,sdm845-llcc"
-
-- reg:
-	Usage: required
-	Value Type: <prop-encoded-array>
-	Definition: The first element specifies the llcc base start address and
-		    the size of the register region. The second element specifies
-		    the llcc broadcast base address and size of the register region.
-
-- reg-names:
-        Usage: required
-        Value Type: <stringlist>
-        Definition: Register region names. Must be "llcc_base", "llcc_broadcast_base".
-
-- interrupts:
-	Usage: required
-	Definition: The interrupt is associated with the llcc edac device.
-			It's used for llcc cache single and double bit error detection
-			and reporting.
-
-Example:
-
-	cache-controller@1100000 {
-		compatible = "qcom,sdm845-llcc";
-		reg = <0x1100000 0x200000>, <0x1300000 0x50000> ;
-		reg-names = "llcc_base", "llcc_broadcast_base";
-		interrupts = <GIC_SPI 582 IRQ_TYPE_LEVEL_HIGH>;

+  LLCC (Last Level Cache Controller) provides last level of cache memory in SoC,
+  that can be shared by multiple clients. Clients here are different cores in the
+  SoC, the idea is to minimize the local caches at the clients and migrate to
+  common pool of memory. Cache memory is divided into partitions called slices
+  which are assigned to clients. Clients can query the slice details, activate
+  and deactivate them.

+OMAP PRM instance bindings
+
+Power and Reset Manager is an IP block on OMAP family of devices which
+handle the power domains and their current state, and provide reset
+handling for the domains and/or separate IP blocks under the power domain
+hierarchy.
+
+Required properties:
+- compatible:	Must contain one of the following:
+		"ti,am3-prm-inst"
+		"ti,am4-prm-inst"
+		"ti,omap4-prm-inst"
+		"ti,omap5-prm-inst"
+		"ti,dra7-prm-inst"
+		and additionally must contain:
+		"ti,omap-prm-inst"
+- reg:		Contains PRM instance register address range
+		(base address and length)
+
+Optional properties:
+- #reset-cells:	Should be 1 if the PRM instance in question supports resets.
+
+Example:
+
+prm_dsp2: prm@1b00 {
+	compatible = "ti,dra7-prm-inst", "ti,omap-prm-inst";
+	reg = <0x1b00 0x40>;

-SAMSUNG Exynos SoC series PMU Registers
-
-Properties:
- - compatible : should contain two values. First value must be one from following list:
-		   - "samsung,exynos3250-pmu" - for Exynos3250 SoC,
-		   - "samsung,exynos4210-pmu" - for Exynos4210 SoC,
-		   - "samsung,exynos4412-pmu" - for Exynos4412 SoC,
-		   - "samsung,exynos5250-pmu" - for Exynos5250 SoC,
-		   - "samsung,exynos5260-pmu" - for Exynos5260 SoC.
-		   - "samsung,exynos5410-pmu" - for Exynos5410 SoC,
-		   - "samsung,exynos5420-pmu" - for Exynos5420 SoC.
-		   - "samsung,exynos5433-pmu" - for Exynos5433 SoC.
-		   - "samsung,exynos7-pmu" - for Exynos7 SoC.
-		second value must be always "syscon".
-
- - reg : offset and length of the register set.
-
- - #clock-cells : must be <1>, since PMU requires once cell as clock specifier.
-		The single specifier cell is used as index to list of clocks
-		provided by PMU, which is currently:
-			0 : SoC clock output (CLKOUT pin)
-
- - clock-names : list of clock names for particular CLKOUT mux inputs in
-		following format:
-			"clkoutN", where N is a decimal number corresponding to
-			CLKOUT mux control bits value for given input, e.g.
-				"clkout0", "clkout7", "clkout15".
-
- - clocks : list of phandles and specifiers to all input clocks listed in
-		clock-names property.
-
-Optional properties:
-
-Some PMUs are capable of behaving as an interrupt controller (mostly
-to wake up a suspended PMU). In which case, they can have the
-following properties:
-
-- interrupt-controller: indicate that said PMU is an interrupt controller
-
-- #interrupt-cells: must be identical to the that of the parent interrupt
-  controller.
-
-
-Optional nodes:
-
-- nodes defining the restart and poweroff syscon children
-
-
-Example :
-pmu_system_controller: system-controller@10040000 {
-	compatible = "samsung,exynos5250-pmu", "syscon";
-	reg = <0x10040000 0x5000>;
-	interrupt-controller;
-	#interrupt-cells = <3>;
-	interrupt-parent = <&gic>;
-	#clock-cells = <1>;
-	clock-names = "clkout0", "clkout1", "clkout2", "clkout3",
-			"clkout4", "clkout8", "clkout9";
-	clocks = <&clock CLK_OUT_DMC>, <&clock CLK_OUT_TOP>,
-		<&clock CLK_OUT_LEFTBUS>, <&clock CLK_OUT_RIGHTBUS>,
-		<&clock CLK_OUT_CPU>, <&clock CLK_XXTI>,
-		<&clock CLK_XUSBXTI>;
-};
-
-Example of clock consumer :
-
-usb3503: usb3503@8 {
-	/* ... */
-	clock-names = "refclk";
-	clocks = <&pmu_system_controller 0>;
-	/* ... */

-Allwinner SRAM for smp bringup:
-------------------------------------------------
-
-Allwinner's A80 SoC uses part of the secure sram for hotplugging of the
-primary core (cpu0). Once the core gets powered up it checks if a magic
-value is set at a specific location. If it is then the BROM will jump
-to the software entry address, instead of executing a standard boot.
-
-Therefore a reserved section sub-node has to be added to the mmio-sram
-declaration.
-
-Note that this is separate from the Allwinner SRAM controller found in
-../../sram/sunxi-sram.txt. This SRAM is secure only and not mappable to
-any device.
-
-Also there are no "secure-only" properties. The implementation should
-check if this SRAM is usable first.
-
-Required sub-node properties:
-- compatible : depending on the SoC this should be one of:
-		"allwinner,sun9i-a80-smp-sram"
-
-The rest of the properties should follow the generic mmio-sram discription
-found in ../../misc/sram.txt
-
-Example:
-
-	sram_b: sram@20000 {
-		/* 256 KiB secure SRAM at 0x20000 */
-		compatible = "mmio-sram";
-		reg = <0x00020000 0x40000>;
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges = <0 0x00020000 0x40000>;
-
-		smp-sram@1000 {
-			/*
-			 * This is checked by BROM to determine if
-			 * cpu0 should jump to SMP entry vector
-			 */
-			compatible = "allwinner,sun9i-a80-smp-sram";
-			reg = <0x1000 0x8>;

-Renesas Bus State Controller (BSC)
-==================================
-
-The Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus
-Bridge", or "External Bus Interface") can be found in several Renesas ARM SoCs.
-It provides an external bus for connecting multiple external devices to the
-SoC, driving several chip select lines, for e.g. NOR FLASH, Ethernet and USB.
-
-While the BSC is a fairly simple memory-mapped bus, it may be part of a PM
-domain, and may have a gateable functional clock.
-Before a device connected to the BSC can be accessed, the PM domain
-containing the BSC must be powered on, and the functional clock
-driving the BSC must be enabled.
-
-The bindings for the BSC extend the bindings for "simple-pm-bus".
-
-
-Required properties
-  - compatible: Must contain an SoC-specific value, and "renesas,bsc" and
-		"simple-pm-bus" as fallbacks.
-                SoC-specific values can be:
-		"renesas,bsc-r8a73a4" for R-Mobile APE6 (r8a73a4)
-		"renesas,bsc-sh73a0" for SH-Mobile AG5 (sh73a0)
-  - #address-cells, #size-cells, ranges: Must describe the mapping between
-		parent address and child address spaces.
-  - reg: Must contain the base address and length to access the bus controller.
-
-Optional properties:
-  - interrupts: Must contain a reference to the BSC interrupt, if available.
-  - clocks: Must contain a reference to the functional clock, if available.
-  - power-domains: Must contain a reference to the PM domain, if available.
-
-
-Example:
-
-	bsc: bus@fec10000 {
-		compatible = "renesas,bsc-sh73a0", "renesas,bsc",

-Simple Power-Managed Bus
-========================
-
-A Simple Power-Managed Bus is a transparent bus that doesn't need a real
-driver, as it's typically initialized by the boot loader.
-
-However, its bus controller is part of a PM domain, or under the control of a
-functional clock.  Hence, the bus controller's PM domain and/or clock must be
-enabled for child devices connected to the bus (either on-SoC or externally)
-to function.
-
-While "simple-pm-bus" follows the "simple-bus" set of properties, as specified
-in the Devicetree Specification, it is not an extension of "simple-bus".
-
-
-Required properties:
-  - compatible: Must contain at least "simple-pm-bus".
-		Must not contain "simple-bus".
-		It's recommended to let this be preceded by one or more
-		vendor-specific compatible values.
-  - #address-cells, #size-cells, ranges: Must describe the mapping between
-		parent address and child address spaces.
-
-Optional platform-specific properties for clock or PM domain control (at least
-one of them is required):
-  - clocks: Must contain a reference to the functional clock(s),
-  - power-domains: Must contain a reference to the PM domain.
-Please refer to the binding documentation for the clock and/or PM domain
-providers for more details.
-
-
-Example:
-
-	bsc: bus@fec10000 {
-		compatible = "renesas,bsc-sh73a0", "renesas,bsc",
-			     "simple-pm-bus";
-		#address-cells = <1>;

-                If <manufacturer> is not "atmel", then a fallback must be used
-                with the same <model> and "atmel" as manufacturer.
-
-                Example:
-                        compatible = "microchip,24c128", "atmel,24c128";
-
-                Supported manufacturers are:
-
-                "catalyst",
-                "microchip",
-                "nxp",

-                "st",
-
-                Some vendors use different model names for chips which are just
-                variants of the above. Known such exceptions are listed below:
-
-                "nxp,se97b" - the fallback is "atmel,24c02",
-                "renesas,r1ex24002" - the fallback is "atmel,24c02"
-                "renesas,r1ex24016" - the fallback is "atmel,24c16"
-                "renesas,r1ex24128" - the fallback is "atmel,24c128"
-                "rohm,br24t01" - the fallback is "atmel,24c01"
-
-  - reg: The I2C address of the EEPROM.
-
-Optional properties:
-
-  - pagesize: The length of the pagesize for writing. Please consult the
-              manual of your device, that value varies a lot. A wrong value
-              may result in data loss! If not specified, a safety value of
-              '1' is used which will be very slow.
-
-  - read-only: This parameterless property disables writes to the eeprom.
-
-  - size: Total eeprom size in bytes.
-
-  - no-read-rollover: This parameterless property indicates that the
-                      multi-address eeprom does not automatically roll over
-                      reads to the next slave address. Please consult the
-                      manual of your device.
-
-  - wp-gpios: GPIO to which the write-protect pin of the chip is connected.
-
-  - address-width: number of address bits (one of 8, 16).
-
-  - num-addresses: total number of i2c slave addresses this device takes
-
-Example:
-
-eeprom@52 {
-	compatible = "atmel,24c32";
-	reg = <0x52>;
-	pagesize = <32>;
-	wp-gpios = <&gpio1 3 0>;
-	num-addresses = <8>;

-New driver handles the following
-1. Supports ADC IF found on EXYNOS4412/EXYNOS5250
-   and future SoCs from Samsung
-2. Add ADC driver under iio/adc framework
-3. Also adds the Documentation for device tree bindings
-
-Required properties:

-* ARM System MMU Architecture Implementation
-
-ARM SoCs may contain an implementation of the ARM System Memory
-Management Unit Architecture, which can be used to provide 1 or 2 stages
-of address translation to bus masters external to the CPU.
-
-The SMMU may also raise interrupts in response to various fault
-conditions.
-
-** System MMU required properties:
-
-- compatible    : Should be one of:
-
-                        "arm,smmu-v1"
-                        "arm,smmu-v2"

-                        "qcom,smmu-v2"
-
-                  depending on the particular implementation and/or the
-                  version of the architecture implemented.
-
-                  Qcom SoCs must contain, as below, SoC-specific compatibles
-                  along with "qcom,smmu-v2":
-                  "qcom,msm8996-smmu-v2", "qcom,smmu-v2",
-                  "qcom,sdm845-smmu-v2", "qcom,smmu-v2".
-
-                  Qcom SoCs implementing "arm,mmu-500" must also include,
-                  as below, SoC-specific compatibles:
-                  "qcom,sdm845-smmu-500", "arm,mmu-500"
-
-- reg           : Base address and size of the SMMU.
-
-- #global-interrupts : The number of global interrupts exposed by the
-                       device.
-
-- interrupts    : Interrupt list, with the first #global-irqs entries
-                  corresponding to the global interrupts and any
-                  following entries corresponding to context interrupts,
-                  specified in order of their indexing by the SMMU.
-
-                  For SMMUv2 implementations, there must be exactly one
-                  interrupt per context bank. In the case of a single,
-                  combined interrupt, it must be listed multiple times.
-
-- #iommu-cells  : See Documentation/devicetree/bindings/iommu/iommu.txt
-                  for details. With a value of 1, each IOMMU specifier
-                  represents a distinct stream ID emitted by that device
-                  into the relevant SMMU.
-
-                  SMMUs with stream matching support and complex masters
-                  may use a value of 2, where the second cell of the
-                  IOMMU specifier represents an SMR mask to combine with
-                  the ID in the first cell.  Care must be taken to ensure
-                  the set of matched IDs does not result in conflicts.
-
-** System MMU optional properties:
-
-- dma-coherent  : Present if page table walks made by the SMMU are
-                  cache coherent with the CPU.
-
-                  NOTE: this only applies to the SMMU itself, not
-                  masters connected upstream of the SMMU.
-
-- calxeda,smmu-secure-config-access : Enable proper handling of buggy
-                  implementations that always use secure access to
-                  SMMU configuration registers. In this case non-secure
-                  aliases of secure registers have to be used during
-                  SMMU configuration.
-
-- stream-match-mask : For SMMUs supporting stream matching and using
-                  #iommu-cells = <1>, specifies a mask of bits to ignore
-		  when matching stream IDs (e.g. this may be programmed
-		  into the SMRn.MASK field of every stream match register
-		  used). For cases where it is desirable to ignore some
-                  portion of every Stream ID (e.g. for certain MMU-500
-                  configurations given globally unique input IDs). This
-                  property is not valid for SMMUs using stream indexing,
-                  or using stream matching with #iommu-cells = <2>, and
-                  may be ignored if present in such cases.
-
-- clock-names:    List of the names of clocks input to the device. The
-                  required list depends on particular implementation and
-                  is as follows:
-                  - for "qcom,smmu-v2":
-                    - "bus": clock required for downstream bus access and
-                             for the smmu ptw,
-                    - "iface": clock required to access smmu's registers
-                               through the TCU's programming interface.
-                  - unspecified for other implementations.
-
-- clocks:         Specifiers for all clocks listed in the clock-names property,
-                  as per generic clock bindings.
-
-- power-domains:  Specifiers for power domains required to be powered on for
-                  the SMMU to operate, as per generic power domain bindings.
-
-** Deprecated properties:
-
-- mmu-masters (deprecated in favour of the generic "iommus" binding) :
-                  A list of phandles to device nodes representing bus
-                  masters for which the SMMU can provide a translation
-                  and their corresponding Stream IDs. Each device node
-                  linked from this list must have a "#stream-id-cells"
-                  property, indicating the number of Stream ID
-                  arguments associated with its phandle.

-Samsung Exynos IOMMU H/W, System MMU (System Memory Management Unit)
-
-Samsung's Exynos architecture contains System MMUs that enables scattered
-physical memory chunks visible as a contiguous region to DMA-capable peripheral
-devices like MFC, FIMC, FIMD, GScaler, FIMC-IS and so forth.
-
-System MMU is an IOMMU and supports identical translation table format to
-ARMv7 translation tables with minimum set of page properties including access
-permissions, shareability and security protection. In addition, System MMU has
-another capabilities like L2 TLB or block-fetch buffers to minimize translation
-latency.
-
-System MMUs are in many to one relation with peripheral devices, i.e. single
-peripheral device might have multiple System MMUs (usually one for each bus
-master), but one System MMU can handle transactions from only one peripheral
-device. The relation between a System MMU and the peripheral device needs to be
-defined in device node of the peripheral device.
-
-MFC in all Exynos SoCs and FIMD, M2M Scalers and G2D in Exynos5420 has 2 System
-MMUs.
-* MFC has one System MMU on its left and right bus.
-* FIMD in Exynos5420 has one System MMU for window 0 and 4, the other system MMU
-  for window 1, 2 and 3.
-* M2M Scalers and G2D in Exynos5420 has one System MMU on the read channel and
-  the other System MMU on the write channel.
-
-For information on assigning System MMU controller to its peripheral devices,
-see generic IOMMU bindings.
-
-Required properties:
-- compatible: Should be "samsung,exynos-sysmmu"
-- reg: A tuple of base address and size of System MMU registers.
-- #iommu-cells: Should be <0>.
-- interrupts: An interrupt specifier for interrupt signal of System MMU,
-	      according to the format defined by a particular interrupt
-	      controller.
-- clock-names: Should be "sysmmu" or a pair of "aclk" and "pclk" to gate
-	       SYSMMU core clocks.
-	       Optional "master" if the clock to the System MMU is gated by
-	       another gate clock other core  (usually main gate clock
-	       of peripheral device this SYSMMU belongs to).
-- clocks: Phandles for respective clocks described by clock-names.
-- power-domains: Required if the System MMU is needed to gate its power.
-	  Please refer to the following document:
-	  Documentation/devicetree/bindings/power/pd-samsung.txt

+* Exynos5422 frequency and voltage scaling for Dynamic Memory Controller device
+
+The Samsung Exynos5422 SoC has DMC (Dynamic Memory Controller) to which the DRAM
+memory chips are connected. The driver is to monitor the controller in runtime
+and switch frequency and voltage. To monitor the usage of the controller in
+runtime, the driver uses the PPMU (Platform Performance Monitoring Unit), which
+is able to measure the current load of the memory.
+When 'userspace' governor is used for the driver, an application is able to
+switch the DMC and memory frequency.
+
+Required properties for DMC device for Exynos5422:
+- compatible: Should be "samsung,exynos5422-dmc".
+- clocks : list of clock specifiers, must contain an entry for each
+  required entry in clock-names for CLK_FOUT_SPLL, CLK_MOUT_SCLK_SPLL,
+  CLK_FF_DOUT_SPLL2, CLK_FOUT_BPLL, CLK_MOUT_BPLL, CLK_SCLK_BPLL,
+  CLK_MOUT_MX_MSPLL_CCORE, CLK_MOUT_MX_MSPLL_CCORE_PHY, CLK_MOUT_MCLK_CDREX,
+- clock-names : should include "fout_spll", "mout_sclk_spll", "ff_dout_spll2",
+  "fout_bpll", "mout_bpll", "sclk_bpll", "mout_mx_mspll_ccore",
+  "mout_mclk_cdrex"  entries
+- devfreq-events : phandles for PPMU devices connected to this DMC.
+- vdd-supply : phandle for voltage regulator which is connected.
+- reg : registers of two CDREX controllers.
+- operating-points-v2 : phandle for OPPs described in v2 definition.
+- device-handle : phandle of the connected DRAM memory device. For more
+	information please refer to documentation file:
+	Documentation/devicetree/bindings/ddr/lpddr3.txt
+- devfreq-events : phandles of the PPMU events used by the controller.
+- samsung,syscon-clk : phandle of the clock register set used by the controller,
+	these registers are used for enabling a 'pause' feature and are not
+	exposed by clock framework but they must be used in a safe way.
+	The register offsets are in the driver code and specyfic for this SoC
+	type.
+
+Optional properties for DMC device for Exynos5422:
+- interrupt-parent : The parent interrupt controller.
+- interrupts : Contains the IRQ line numbers for the DMC internal performance
+  event counters in DREX0 and DREX1 channels. Align with specification of the
+  interrupt line(s) in the interrupt-parent controller.
+- interrupt-names : IRQ names "drex_0" and "drex_1", the order should be the
+  same as in the 'interrupts' list above.
+
+Example:
+
+	ppmu_dmc0_0: ppmu@10d00000 {
+		compatible = "samsung,exynos-ppmu";
+		reg = <0x10d00000 0x2000>;

+description: |
+  The EMC interfaces with the off-chip SDRAM to service the request stream
+  sent from Memory Controller. The EMC also has various performance-affecting
+  settings beyond the obvious SDRAM configuration parameters and initialization
+  settings. Tegra30 EMC supports multiple JEDEC standard protocols: LPDDR2,
+  LPDDR3, and DDR3.

+description: |
+  Tegra30 Memory Controller architecturally consists of the following parts:
+
+    Arbitration Domains, which can handle a single request or response per
+    clock from a group of clients. Typically, a system has a single Arbitration
+    Domain, but an implementation may divide the client space into multiple
+    Arbitration Domains to increase the effective system bandwidth.
+
+    Protocol Arbiter, which manage a related pool of memory devices. A system
+    may have a single Protocol Arbiter or multiple Protocol Arbiters.
+
+    Memory Crossbar, which routes request and responses between Arbitration
+    Domains and Protocol Arbiters. In the simplest version of the system, the
+    Memory Crossbar is just a pass through between a single Arbitration Domain
+    and a single Protocol Arbiter.
+
+    Global Resources, which include things like configuration registers which
+    are shared across the Memory Subsystem.
+
+  The Tegra30 Memory Controller handles memory requests from internal clients
+  and arbitrates among them to allocate memory bandwidth for DDR3L and LPDDR2
+  SDRAMs.

-Generic SYSCON mapped register poweroff driver
-
-This is a generic poweroff driver using syscon to map the poweroff register.
-The poweroff is generally performed with a write to the poweroff register
-defined by the register map pointed by syscon reference plus the offset
-with the value and mask defined in the poweroff node.
-
-Required properties:
-- compatible: should contain "syscon-poweroff"
-- regmap: this is phandle to the register map node
-- offset: offset in the register map for the poweroff register (in bytes)
-- value: the poweroff value written to the poweroff register (32 bit access)
-
-Optional properties:
-- mask: update only the register bits defined by the mask (32 bit)
-
-Legacy usage:
-If a node doesn't contain a value property but contains a mask property, the
-mask property is used as the value.
-
-Default will be little endian mode, 32 bit access only.
-
-Examples:
-
-	poweroff {
-	   compatible = "syscon-poweroff";
-	   regmap = <&regmapnode>;
-	   offset = <0x0>;
-	   mask = <0x7a>;

+NVIDIA Tegra Regulators Coupling
+================================
+
+NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
+Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
+there are 2.
+
+Tegra20 voltage coupling
+------------------------
+
+On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
+The CORE and RTC voltages shall be in a range of 170mV from each other
+and they both shall be higher than the CPU voltage by at least 120mV.
+
+Tegra30 voltage coupling
+------------------------
+
+On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
+and CPU voltages shall be in a range of 300mV from each other and CORE
+voltage shall be higher than the CPU by N mV, where N depends on the CPU
+voltage.
+
+Required properties:
+- nvidia,tegra-core-regulator: Boolean property that designates regulator
+  as the "Core domain" voltage regulator.
+- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
+  as the "RTC domain" voltage regulator.
+- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
+  as the "CPU domain" voltage regulator.
+
+Example:
+
+	pmic {
+		regulators {
+			core_vdd_reg: core {
+				regulator-name = "vdd_core";
+				regulator-min-microvolt = <950000>;
+				regulator-max-microvolt = <1300000>;
+				regulator-coupled-with = <&rtc_vdd_reg &cpu_vdd_reg>;
+				regulator-coupled-max-spread = <170000 550000>;
+
+				nvidia,tegra-core-regulator;
+			};
+
+			rtc_vdd_reg: rtc {
+				regulator-name = "vdd_rtc";
+				regulator-min-microvolt = <950000>;
+				regulator-max-microvolt = <1300000>;
+				regulator-coupled-with = <&core_vdd_reg &cpu_vdd_reg>;

-Amlogic Canvas
-================================
-
-A canvas is a collection of metadata that describes a pixel buffer.
-Those metadata include: width, height, phyaddr, wrapping and block mode.
-Starting with GXBB the endianness can also be described.
-
-Many IPs within Amlogic SoCs rely on canvas indexes to read/write pixel data
-rather than use the phy addresses directly. For instance, this is the case for
-the video decoders and the display.
-
-Amlogic SoCs have 256 canvas.

-* Renesas SMP SRAM
-
-Renesas R-Car Gen2 and RZ/G1 SoCs need a small piece of SRAM for the jump stub
-for secondary CPU bringup and CPU hotplug.
-This memory is reserved by adding a child node to a "mmio-sram" node, cfr.

-Rockchip SRAM for smp bringup:
-------------------------------

-

-Samsung Exynos SYSRAM for SMP bringup:
-------------------------------------
-

-Required sub-node properties:

-Binding for Thermal Sensor for STMicroelectronics STM32 series of SoCs.
-
-On STM32 SoCs, the Digital Temperature Sensor (DTS) is in charge of managing an
-analog block which delivers a frequency depending on the internal SoC's
-temperature. By using a reference frequency, DTS is able to provide a sample
-number which can be translated into a temperature by the user.
-
-DTS provides interrupt notification mechanism by threshold. This mechanism
-offers two temperature trip points: passive and critical. The first is intended
-for passive cooling notification while the second is used for over-temperature
-reset.
-
-Required parameters:
--------------------
-
-compatible: 	Should be "st,stm32-thermal"
-reg: 		This should be the physical base address and length of the
-		sensor's registers.
-clocks: 	Phandle of the clock used by the thermal sensor.
-		  See: Documentation/devicetree/bindings/clock/clock-bindings.txt
-clock-names: 	Should be "pclk" for register access clock and reference clock.
-		  See: Documentation/devicetree/bindings/resource-names.txt
-#thermal-sensor-cells: Should be 0. See ./thermal.txt for a description.
-interrupts:	Standard way to define interrupt number.
-
-Example:
-
-	thermal-zones {
-		cpu_thermal: cpu-thermal {
-			polling-delay-passive = <0>;
-			polling-delay = <0>;
-
-			thermal-sensors = <&thermal>;

-					hysteresis = <0>;

-					temperature = <120000>;
-					hysteresis = <0>;
-					type = "critical";
-				};
-			};
-
-			cooling-maps {
-			};
-		};

-Samsung's Multi Core Timer (MCT)
-
-The Samsung's Multi Core Timer (MCT) module includes two main blocks, the
-global timer and CPU local timers. The global timer is a 64-bit free running
-up-counter and can generate 4 interrupts when the counter reaches one of the
-four preset counter values. The CPU local timers are 32-bit free running
-down-counters and generate an interrupt when the counter expires. There is
-one CPU local timer instantiated in MCT for every CPU in the system.
-
-Required properties:
-
-- compatible: should be "samsung,exynos4210-mct".
-  (a) "samsung,exynos4210-mct", for mct compatible with Exynos4210 mct.
-  (b) "samsung,exynos4412-mct", for mct compatible with Exynos4412 mct.
-
-- reg: base address of the mct controller and length of the address space
-  it occupies.
-
-- interrupts: the list of interrupts generated by the controller. The following
-  should be the order of the interrupts specified. The local timer interrupts
-  should be specified after the four global timer interrupts have been
-  specified.
-
-	0: Global Timer Interrupt 0
-	1: Global Timer Interrupt 1
-	2: Global Timer Interrupt 2
-	3: Global Timer Interrupt 3
-	4: Local Timer Interrupt 0
-	5: Local Timer Interrupt 1
-	6: ..
-	7: ..
-	i: Local Timer Interrupt n
-
-  For MCT block that uses a per-processor interrupt for local timers, such
-  as ones compatible with "samsung,exynos4412-mct", only one local timer
-  interrupt might be specified, meaning that all local timers use the same
-  per processor interrupt.
-
-Example 1: In this example, the IP contains two local timers, using separate
-	   interrupts, so two local timer interrupts have been specified,
-	   in addition to four global timer interrupts.
-
-	mct@10050000 {
-		compatible = "samsung,exynos4210-mct";
-		reg = <0x10050000 0x800>;
-		interrupts = <0 57 0>, <0 69 0>, <0 70 0>, <0 71 0>,
-			     <0 42 0>, <0 48 0>;
-	};
-
-Example 2: In this example, the timer interrupts are connected to two separate
-	   interrupt controllers. Hence, an interrupt-map is created to map
-	   the interrupts to the respective interrupt controllers.
-
-	mct@101c0000 {
-		compatible = "samsung,exynos4210-mct";
-		reg = <0x101C0000 0x800>;
-		interrupt-parent = <&mct_map>;
-		interrupts = <0>, <1>, <2>, <3>, <4>, <5>;
-
-		mct_map: mct-map {
-			#interrupt-cells = <1>;
-			#address-cells = <0>;
-			#size-cells = <0>;
-			interrupt-map = <0 &gic 0 57 0>,
-					<1 &gic 0 69 0>,
-					<2 &combiner 12 6>,
-					<3 &combiner 12 7>,
-					<4 &gic 0 42 0>,
-					<5 &gic 0 48 0>;
-		};
-	};
-
-Example 3: In this example, the IP contains four local timers, but using
-	   a per-processor interrupt to handle them. Either all the local
-	   timer interrupts can be specified, with the same interrupt specifier
-	   value or just the first one.
-
-	mct@10050000 {
-		compatible = "samsung,exynos4412-mct";
-		reg = <0x10050000 0x800>;

-Amlogic Meson G12A DWC3 USB SoC Controller Glue
-
-The Amlogic G12A embeds a DWC3 USB IP Core configured for USB2 and USB3
-in host-only mode, and a DWC2 IP Core configured for USB2 peripheral mode
-only.
-
-A glue connects the DWC3 core to USB2 PHYs and optionnaly to an USB3 PHY.
-
-One of the USB2 PHY can be re-routed in peripheral mode to a DWC2 USB IP.
-
-The DWC3 Glue controls the PHY routing and power, an interrupt line is
-connected to the Glue to serve as OTG ID change detection.
-
-Required properties:
-- compatible:	Should be "amlogic,meson-g12a-usb-ctrl"
-- clocks:	a handle for the "USB" clock
-- resets:	a handle for the shared "USB" reset line
-- reg:		The base address and length of the registers
-- interrupts:	the interrupt specifier for the OTG detection
-- phys: 	handle to used PHYs on the system
-	- a <0> phandle can be used if a PHY is not used
-- phy-names:	names of the used PHYs on the system :
-	- "usb2-phy0" for USB2 PHY0 if USBHOST_A port is used
-	- "usb2-phy1" for USB2 PHY1 if USBOTG_B port is used
-	- "usb3-phy0" for USB3 PHY if USB3_0 is used
-- dr_mode:	should be "host", "peripheral", or "otg" depending on
-	the usage and configuration of the OTG Capable port.
-	- "host" and "peripheral" means a fixed Host or Device only connection
-	- "otg" means the port can be used as both Host or Device and
-	  be switched automatically using the OTG ID pin.
-
-Optional properties:
-- vbus-supply:	should be a phandle to the regulator controlling the VBUS
-		power supply when used in OTG switchable mode

+Maintainer Entry Profile
+========================
+
+The Maintainer Entry Profile supplements the top-level process documents
+(submitting-patches, submitting drivers...) with
+subsystem/device-driver-local customs as well as details about the patch
+submission life-cycle. A contributor uses this document to level set
+their expectations and avoid common mistakes, maintainers may use these
+profiles to look across subsystems for opportunities to converge on
+common practices.
+
+
+Overview
+--------
+Provide an introduction to how the subsystem operates. While MAINTAINERS
+tells the contributor where to send patches for which files, it does not
+convey other subsystem-local infrastructure and mechanisms that aid
+development.
+
+Example questions to consider:
+
+- Are there notifications when patches are applied to the local tree, or
+  merged upstream?
+- Does the subsystem have a patchwork instance? Are patchwork state
+  changes notified?
+- Any bots or CI infrastructure that watches the list, or automated
+  testing feedback that the subsystem gates acceptance?
+- Git branches that are pulled into -next?
+- What branch should contributors submit against?
+- Links to any other Maintainer Entry Profiles? For example a
+  device-driver may point to an entry for its parent subsystem. This makes
+  the contributor aware of obligations a maintainer may have have for
+  other maintainers in the submission chain.
+
+
+Submit Checklist Addendum
+-------------------------
+List mandatory and advisory criteria, beyond the common "submit-checklist",
+for a patch to be considered healthy enough for maintainer attention.
+For example: "pass checkpatch.pl with no errors, or warning. Pass the
+unit test detailed at $URI".
+
+The Submit Checklist Addendum can also include details about the status
+of related hardware specifications. For example, does the subsystem
+require published specifications at a certain revision before patches
+will be considered.
+
+
+Key Cycle Dates
+---------------
+One of the common misunderstandings of submitters is that patches can be
+sent at any time before the merge window closes and can still be
+considered for the next -rc1. The reality is that most patches need to
+be settled in soaking in linux-next in advance of the merge window
+opening. Clarify for the submitter the key dates (in terms rc release
+week) that patches might considered for merging and when patches need to
+wait for the next -rc. At a minimum:
+
+- Last -rc for new feature submissions:
+  New feature submissions targeting the next merge window should have
+  their first posting for consideration before this point. Patches that
+  are submitted after this point should be clear that they are targeting
+  the NEXT+1 merge window, or should come with sufficient justification
+  why they should be considered on an expedited schedule. A general
+  guideline is to set expectation with contributors that new feature
+  submissions should appear before -rc5.
+
+- Last -rc to merge features: Deadline for merge decisions
+  Indicate to contributors the point at which an as yet un-applied patch
+  set will need to wait for the NEXT+1 merge window. Of course there is no
+  obligation to ever except any given patchset, but if the review has not
+  concluded by this point the expectation the contributor should wait and
+  resubmit for the following merge window.
+
+Optional:
+
+- First -rc at which the development baseline branch, listed in the
+  overview section, should be considered ready for new submissions.
+
+
+Review Cadence
+--------------
+One of the largest sources of contributor angst is how soon to ping
+after a patchset has been posted without receiving any feedback. In
+addition to specifying how long to wait before a resubmission this
+section can also indicate a preferred style of update like, resend the
+full series, or privately send a reminder email. This section might also
+list how review works for this code area and methods to get feedback
+that are not directly from the maintainer.
+
+Existing profiles
+-----------------
+
+For now, existing maintainer profiles are listed here; we will likely want
+to do something different in the near future.

+Xilinx SD-FEC Driver
+====================
+
+Overview
+========
+
+This driver supports SD-FEC Integrated Block for Zynq |Ultrascale+ (TM)| RFSoCs.
+
+.. |Ultrascale+ (TM)| unicode:: Ultrascale+ U+2122
+   .. with trademark sign
+
+For a full description of SD-FEC core features, see the `SD-FEC Product Guide (PG256) <https://www.xilinx.com/cgi-bin/docs/ipdoc?c=sd_fec;v=latest;d=pg256-sdfec-integrated-block.pdf>`_
+
+This driver supports the following features:
+
+  - Retrieval of the Integrated Block configuration and status information
+  - Configuration of LDPC codes
+  - Configuration of Turbo decoding
+  - Monitoring errors
+
+Missing features, known issues, and limitations of the SD-FEC driver are as
+follows:
+
+  - Only allows a single open file handler to any instance of the driver at any time
+  - Reset of the SD-FEC Integrated Block is not controlled by this driver
+  - Does not support shared LDPC code table wraparound
+
+The device tree entry is described in:
+`linux-xlnx/Documentation/devicetree/bindings/misc/xlnx,sd-fec.txt <https://github.com/Xilinx/linux-xlnx/blob/master/Documentation/devicetree/bindings/misc/xlnx%2Csd-fec.txt>`_
+
+
+Modes of Operation
+------------------
+
+The driver works with the SD-FEC core in two modes of operation:
+
+  - Run-time configuration
+  - Programmable Logic (PL) initialization
+
+
+Run-time Configuration
+~~~~~~~~~~~~~~~~~~~~~~
+
+For Run-time configuration the role of driver is to allow the software application to do the following:
+
+	- Load the configuration parameters for either Turbo decode or LDPC encode or decode
+	- Activate the SD-FEC core
+	- Monitor the SD-FEC core for errors
+	- Retrieve the status and configuration of the SD-FEC core
+
+Programmable Logic (PL) Initialization
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For PL initialization, supporting logic loads configuration parameters for either
+the Turbo decode or LDPC encode or decode.  The role of the driver is to allow
+the software application to do the following:
+
+	- Activate the SD-FEC core
+	- Monitor the SD-FEC core for errors
+	- Retrieve the status and configuration of the SD-FEC core
+
+
+Driver Structure
+================
+
+The driver provides a platform device where the ``probe`` and ``remove``
+operations are provided.
+
+  - probe: Updates configuration register with device-tree entries plus determines the current activate state of the core, for example, is the core bypassed or has the core been started.
+
+
+The driver defines the following driver file operations to provide user
+application interfaces:
+
+  - open: Implements restriction that only a single file descriptor can be open per SD-FEC instance at any time
+  - release: Allows another file descriptor to be open, that is after current file descriptor is closed
+  - poll: Provides a method to monitor for SD-FEC Error events
+  - unlocked_ioctl: Provides the the following ioctl commands that allows the application configure the SD-FEC core:
+
+		- :c:macro:`XSDFEC_START_DEV`
+		- :c:macro:`XSDFEC_STOP_DEV`
+		- :c:macro:`XSDFEC_GET_STATUS`
+		- :c:macro:`XSDFEC_SET_IRQ`
+		- :c:macro:`XSDFEC_SET_TURBO`
+		- :c:macro:`XSDFEC_ADD_LDPC_CODE_PARAMS`
+		- :c:macro:`XSDFEC_GET_CONFIG`
+		- :c:macro:`XSDFEC_SET_ORDER`
+		- :c:macro:`XSDFEC_SET_BYPASS`
+		- :c:macro:`XSDFEC_IS_ACTIVE`
+		- :c:macro:`XSDFEC_CLEAR_STATS`
+		- :c:macro:`XSDFEC_SET_DEFAULT_CONFIG`
+
+
+Driver Usage
+============
+
+
+Overview
+--------
+
+After opening the driver, the user should find out what operations need to be
+performed to configure and activate the SD-FEC core and determine the
+configuration of the driver.
+The following outlines the flow the user should perform:
+
+  - Determine Configuration
+  - Set the order, if not already configured as desired
+  - Set Turbo decode, LPDC encode or decode parameters, depending on how the
+    SD-FEC core is configured plus if the SD-FEC has not been configured for PL
+    initialization
+  - Enable interrupts, if not already enabled
+  - Bypass the SD-FEC core, if required
+  - Start the SD-FEC core if not already started
+  - Get the SD-FEC core status
+  - Monitor for interrupts
+  - Stop the SD-FEC core
+
+
+Note: When monitoring for interrupts if a critical error is detected where a reset is required, the driver will be required to load the default configuration.
+
+
+Determine Configuration
+-----------------------
+
+Determine the configuration of the SD-FEC core by using the ioctl
+:c:macro:`XSDFEC_GET_CONFIG`.
+
+Set the Order
+-------------
+
+Setting the order determines how the order of Blocks can change from input to output.
+
+Setting the order is done by using the ioctl :c:macro:`XSDFEC_SET_ORDER`
+
+Setting the order can only be done if the following restrictions are met:
+
+	- The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+
+Add LDPC Codes
+--------------
+
+The following steps indicate how to add LDPC codes to the SD-FEC core:
+
+	- Use the auto-generated parameters to fill the :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>` for the desired LDPC code.
+	- Set the SC, QA, and LA table offsets for the LPDC parameters and the parameters in the structure :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>`
+	- Set the desired Code Id value in the structure :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>`
+	- Add the LPDC Code Parameters using the ioctl :c:macro:`XSDFEC_ADD_LDPC_CODE_PARAMS`
+	- For the applied LPDC Code Parameter use the function :c:func:`xsdfec_calculate_shared_ldpc_table_entry_size` to calculate the size of shared LPDC code tables. This allows the user to determine the shared table usage so when selecting the table offsets for the next LDPC code parameters unused table areas can be selected.
+	- Repeat for each LDPC code parameter.
+
+Adding LDPC codes can only be done if the following restrictions are met:
+
+	- The ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as LDPC
+	- The ``code_wr_protect`` of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates that write protection is not enabled
+	- The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not started
+
+Set Turbo Decode
+----------------
+
+Configuring the Turbo decode parameters is done by using the ioctl :c:macro:`XSDFEC_SET_TURBO` using auto-generated parameters to fill the :c:type:`struct xsdfec_turbo <xsdfec_turbo>` for the desired Turbo code.
+
+Adding Turbo decode can only be done if the following restrictions are met:
+
+	- The ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as TURBO
+	- The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+Enable Interrupts
+-----------------
+
+Enabling or disabling interrupts is done by using the ioctl :c:macro:`XSDFEC_SET_IRQ`. The members of the parameter passed, :c:type:`struct xsdfec_irq <xsdfec_irq>`, to the ioctl are used to set and clear different categories of interrupts. The category of interrupt is controlled as following:
+
+  - ``enable_isr`` controls the ``tlast`` interrupts
+  - ``enable_ecc_isr`` controls the ECC interrupts
+
+If the ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as TURBO then the enabling ECC errors is not required.
+
+Bypass the SD-FEC
+-----------------
+
+Bypassing the SD-FEC is done by using the ioctl :c:macro:`XSDFEC_SET_BYPASS`
+
+Bypassing the SD-FEC can only be done if the following restrictions are met:
+
+	- The ``state`` member of :c:type:`struct xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+Start the SD-FEC core
+---------------------
+
+Start the SD-FEC core by using the ioctl :c:macro:`XSDFEC_START_DEV`
+
+Get SD-FEC Status
+-----------------
+
+Get the SD-FEC status of the device by using the ioctl :c:macro:`XSDFEC_GET_STATUS`, which will fill the :c:type:`struct xsdfec_status <xsdfec_status>`
+
+Monitor for Interrupts
+----------------------
+
+	- Use the poll system call to monitor for an interrupt. The poll system call waits for an interrupt to wake it up or times out if no interrupt occurs.
+	- On return Poll ``revents`` will indicate whether stats and/or state have been updated
+		- ``POLLPRI`` indicates a critical error and the user should use :c:macro:`XSDFEC_GET_STATUS` and :c:macro:`XSDFEC_GET_STATS` to confirm
+		- ``POLLRDNORM`` indicates a non-critical error has occurred and the user should use  :c:macro:`XSDFEC_GET_STATS` to confirm
+	- Get stats by using the ioctl :c:macro:`XSDFEC_GET_STATS`
+		- For critical error the ``isr_err_count`` or ``uecc_count`` member  of :c:type:`struct xsdfec_stats <xsdfec_stats>` is non-zero
+		- For non-critical errors the ``cecc_count`` member of :c:type:`struct xsdfec_stats <xsdfec_stats>` is non-zero
+	- Get state by using the ioctl :c:macro:`XSDFEC_GET_STATUS`
+		- For a critical error the ``state`` of :c:type:`xsdfec_status <xsdfec_status>` will indicate a Reset Is Required
+	- Clear stats by using the ioctl :c:macro:`XSDFEC_CLEAR_STATS`
+
+If a critical error is detected where a reset is required. The application is required to call the ioctl :c:macro:`XSDFEC_SET_DEFAULT_CONFIG`, after the reset and it is not required to call the ioctl :c:macro:`XSDFEC_STOP_DEV`
+
+Note: Using poll system call prevents busy looping using :c:macro:`XSDFEC_GET_STATS` and :c:macro:`XSDFEC_GET_STATUS`
+
+Stop the SD-FEC Core
+---------------------
+
+Stop the device by using the ioctl :c:macro:`XSDFEC_STOP_DEV`
+
+Set the Default Configuration
+-----------------------------
+
+Load default configuration by using the ioctl :c:macro:`XSDFEC_SET_DEFAULT_CONFIG` to restore the driver.
+
+Limitations
+-----------
+
+Users should not duplicate SD-FEC device file handlers, for example fork() or dup() a process that has a created an SD-FEC file handler.

+LIBNVDIMM Maintainer Entry Profile
+==================================
+
+Overview
+--------
+The libnvdimm subsystem manages persistent memory across multiple
+architectures. The mailing list, is tracked by patchwork here:
+https://patchwork.kernel.org/project/linux-nvdimm/list/
+...and that instance is configured to give feedback to submitters on
+patch acceptance and upstream merge. Patches are merged to either the
+'libnvdimm-fixes', or 'libnvdimm-for-next' branch. Those branches are
+available here:
+https://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git/
+
+In general patches can be submitted against the latest -rc, however if
+the incoming code change is dependent on other pending changes then the
+patch should be based on the libnvdimm-for-next branch. However, since
+persistent memory sits at the intersection of storage and memory there
+are cases where patches are more suitable to be merged through a
+Filesystem or the Memory Management tree. When in doubt copy the nvdimm
+list and the maintainers will help route.
+
+Submissions will be exposed to the kbuild robot for compile regression
+testing. It helps to get a success notification from that infrastructure
+before submitting, but it is not required.
+
+
+Submit Checklist Addendum
+-------------------------
+There are unit tests for the subsystem via the ndctl utility:
+https://github.com/pmem/ndctl
+Those tests need to be passed before the patches go upstream, but not
+necessarily before initial posting. Contact the list if you need help
+getting the test environment set up.
+
+### ACPI Device Specific Methods (_DSM)
+Before patches enabling for a new _DSM family will be considered it must
+be assigned a format-interface-code from the NVDIMM Sub-team of the ACPI
+Specification Working Group. In general, the stance of the subsystem is
+to push back on the proliferation of NVDIMM command sets, do strongly
+consider implementing support for an existing command set. See
+drivers/acpi/nfit/nfit.h for the set of support command sets.
+
+
+Key Cycle Dates
+---------------
+New submissions can be sent at any time, but if they intend to hit the
+next merge window they should be sent before -rc4, and ideally
+stabilized in the libnvdimm-for-next branch by -rc6. Of course if a
+patch set requires more than 2 weeks of review -rc4 is already too late
+and some patches may require multiple development cycles to review.
+
+
+Review Cadence
+--------------
+In general, please wait up to one week before pinging for feedback. A
+private mail reminder is preferred. Alternatively ask for other
+developers that have Reviewed-by tags for libnvdimm changes to take a
+look and offer their opinion.

-16) Sending ``git pull`` requests
+16) Providing base tree information
+-----------------------------------
+
+When other developers receive your patches and start the review process,
+it is often useful for them to know where in the tree history they
+should place your work. This is particularly useful for automated CI
+processes that attempt to run a series of tests in order to establish
+the quality of your submission before the maintainer starts the review.
+
+If you are using ``git format-patch`` to generate your patches, you can
+automatically include the base tree information in your submission by
+using the ``--base`` flag. The easiest and most convenient way to use
+this option is with topical branches::
+
+    $ git checkout -t -b my-topical-branch master
+    Branch 'my-topical-branch' set up to track local branch 'master'.
+    Switched to a new branch 'my-topical-branch'
+
+    [perform your edits and commits]
+
+    $ git format-patch --base=auto --cover-letter -o outgoing/ master
+    outgoing/0000-cover-letter.patch
+    outgoing/0001-First-Commit.patch
+    outgoing/...
+
+When you open ``outgoing/0000-cover-letter.patch`` for editing, you will
+notice that it will have the ``base-commit:`` trailer at the very
+bottom, which provides the reviewer and the CI tools enough information
+to properly perform ``git am`` without worrying about conflicts::
+
+    $ git checkout -b patch-review [base-commit-id]
+    Switched to a new branch 'patch-review'
+    $ git am patches.mbox
+    Applying: First Commit
+    Applying: ...
+
+Please see ``man git-format-patch`` for more information about this
+option.
+
+.. note::
+
+    The ``--base`` feature was introduced in git version 2.9.0.
+
+If you are not using git to format your patches, you can still include
+the same ``base-commit`` trailer to indicate the commit hash of the tree
+on which your work is based. You should add it either in the cover
+letter or in the first patch of the series and it should be placed
+either below the ``---`` line or at the very bottom of all other
+content, right before your email signature.

+===============================================
+
+    :Author:   Mike Leach <mike.leach@linaro.org>
+    :Date:     October 11th, 2019
+
+Supplement to existing ETMv4 driver documentation.

+---------------------------
+
+Root: ``/sys/bus/coresight/devices/etm<N>``

+:File:            ``mode`` (rw)
+:Trace Registers: {CONFIGR + others}
+:Notes:
+    Bit select trace features. See ‘mode’ section below. Bits
+    in this will cause equivalent programming of trace config and
+    other registers to enable the features requested.
+
+:Syntax & eg:
+    ``echo bitfield > mode``
+
+    bitfield up to 32 bits setting trace features.

+*Note:* When programming any address comparator the driver will tag the
+comparator with a type used - i.e. RANGE, SINGLE, START, STOP. Once this tag
+is set, then only the values can be changed using the same sysfs file / type
+used to program it.
+
+Thus::
+
+  % echo 0 > addr_idx		; select address comparator 0
+  % echo 0x1000 0x5000 0 > addr_range ; set address range on comparators 0, 1.
+  % echo 0x2000 > addr_start    ; error as comparator 0 is a range comparator
+  % echo 2 > addr_idx		; select address comparator 2
+  % echo 0x2000 > addr_start	; this is OK as comparator 2 is unused.
+  % echo 0x3000 > addr_stop	; error as comparator 2 set as start address.
+  % echo 2 > addr_idx		; select address comparator 3
+  % echo 0x3000 > addr_stop	; this is OK
+
+To remove programming on all the comparators (and all the other hardware) use
+the reset parameter::
+
+  % echo 1 > reset
+
+
+
+The ‘mode’ sysfs parameter.
+---------------------------
+
+This is a bitfield selection parameter that sets the overall trace mode for the
+ETM. The table below describes the bits, using the defines from the driver
+source file, along with a description of the feature these represent. Many
+features are optional and therefore dependent on implementation in the
+hardware.
+
+Bit assignments shown below:-
+
+----
+
+**bit (0):**
+    ETM_MODE_EXCLUDE
+
+**description:**
+    This is the default value for the include / exclude function when
+    setting address ranges. Set 1 for exclude range. When the mode
+    parameter is set this value is applied to the currently indexed
+    address range.
+
+
+**bit (4):**
+    ETM_MODE_BB
+
+**description:**
+    Set to enable branch broadcast if supported in hardware [IDR0].
+
+
+**bit (5):**
+    ETMv4_MODE_CYCACC
+
+**description:**
+    Set to enable cycle accurate trace if supported [IDR0].
+
+
+**bit (6):**
+    ETMv4_MODE_CTXID
+
+**description:**
+    Set to enable context ID tracing if supported in hardware [IDR2].
+
+
+**bit (7):**
+    ETM_MODE_VMID
+
+**description:**
+    Set to enable virtual machine ID tracing if supported [IDR2].
+
+
+**bit (11):**
+    ETMv4_MODE_TIMESTAMP
+
+**description:**
+    Set to enable timestamp generation if supported [IDR0].
+
+
+**bit (12):**
+    ETM_MODE_RETURNSTACK
+**description:**
+    Set to enable trace return stack use if supported [IDR0].
+
+
+**bit (13-14):**
+    ETM_MODE_QELEM(val)
+
+**description:**
+    ‘val’ determines level of Q element support enabled if
+    implemented by the ETM [IDR0]
+
+
+**bit (19):**
+    ETM_MODE_ATB_TRIGGER
+
+**description:**
+    Set to enable the ATBTRIGGER bit in the event control register
+    [EVENTCTLR1] if supported [IDR5].
+
+
+**bit (20):**
+    ETM_MODE_LPOVERRIDE
+
+**description:**
+    Set to enable the LPOVERRIDE bit in the event control register
+    [EVENTCTLR1], if supported [IDR5].
+
+
+**bit (21):**
+    ETM_MODE_ISTALL_EN
+
+**description:**
+    Set to enable the ISTALL bit in the stall control register
+    [STALLCTLR]
+
+
+**bit (23):**
+    ETM_MODE_INSTPRIO
+
+**description:**
+	      Set to enable the INSTPRIORITY bit in the stall control register
+	      [STALLCTLR] , if supported [IDR0].
+
+
+**bit (24):**
+    ETM_MODE_NOOVERFLOW
+
+**description:**
+    Set to enable the NOOVERFLOW bit in the stall control register
+    [STALLCTLR], if supported [IDR3].
+
+
+**bit (25):**
+    ETM_MODE_TRACE_RESET
+
+**description:**
+    Set to enable the TRCRESET bit in the viewinst control register
+    [VICTLR] , if supported [IDR3].
+
+
+**bit (26):**
+    ETM_MODE_TRACE_ERR
+
+**description:**
+    Set to enable the TRCCTRL bit in the viewinst control register
+    [VICTLR].
+
+
+**bit (27):**
+    ETM_MODE_VIEWINST_STARTSTOP
+
+**description:**
+    Set the initial state value of the ViewInst start / stop logic
+    in the viewinst control register [VICTLR]
+
+
+**bit (30):**
+    ETM_MODE_EXCL_KERN
+
+**description:**
+    Set default trace setup to exclude kernel mode trace (see note a)
+
+
+**bit (31):**
+    ETM_MODE_EXCL_USER
+
+**description:**
+    Set default trace setup to exclude user space trace (see note a)
+
+----
+
+*Note a)* On startup the ETM is programmed to trace the complete address space
+using address range comparator 0. ‘mode’ bits 30 / 31 modify this setting to
+set EL exclude bits for NS state in either user space (EL0) or kernel space
+(EL1) in the address range comparator. (the default setting excludes all
+secure EL, and NS EL2)
+
+Once the reset parameter has been used, and/or custom programming has been
+implemented - using these bits will result in the EL bits for address
+comparator 0 being set in the same way.
+
+*Note b)* Bits 2-3, 8-10, 15-16, 18, 22, control features that only work with
+data trace. As A-profile data trace is architecturally prohibited in ETMv4,
+these have been omitted here. Possible uses could be where a kernel has
+support for control of R or M profile infrastructure as part of a heterogeneous
+system.
+
+Bits 17, 28-29 are unused.

+
+/*
+ * A pseries guest can be run as secure guest on Ultravisor-enabled
+ * POWER platforms. On such platforms, this driver will be used to manage
+ * the movement of guest pages between the normal memory managed by
+ * hypervisor (HV) and secure memory managed by Ultravisor (UV).
+ *
+ * The page-in or page-out requests from UV will come to HV as hcalls and
+ * HV will call back into UV via ultracalls to satisfy these page requests.
+ *
+ * Private ZONE_DEVICE memory equal to the amount of secure memory
+ * available in the platform for running secure guests is hotplugged.
+ * Whenever a page belonging to the guest becomes secure, a page from this
+ * private device memory is used to represent and track that secure page
+ * on the HV side. Some pages (like virtio buffers, VPA pages etc) are
+ * shared between UV and HV. However such pages aren't represented by
+ * device private memory and mappings to shared memory exist in both
+ * UV and HV page tables.
+ */
+
+/*
+ * Notes on locking
+ *
+ * kvm->arch.uvmem_lock is a per-guest lock that prevents concurrent
+ * page-in and page-out requests for the same GPA. Concurrent accesses
+ * can either come via UV (guest vCPUs requesting for same page)
+ * or when HV and guest simultaneously access the same page.
+ * This mutex serializes the migration of page from HV(normal) to
+ * UV(secure) and vice versa. So the serialization points are around
+ * migrate_vma routines and page-in/out routines.
+ *
+ * Per-guest mutex comes with a cost though. Mainly it serializes the
+ * fault path as page-out can occur when HV faults on accessing secure
+ * guest pages. Currently UV issues page-in requests for all the guest
+ * PFNs one at a time during early boot (UV_ESM uvcall), so this is
+ * not a cause for concern. Also currently the number of page-outs caused
+ * by HV touching secure pages is very very low. If an when UV supports
+ * overcommitting, then we might see concurrent guest driven page-outs.
+ *
+ * Locking order
+ *
+ * 1. kvm->srcu - Protects KVM memslots
+ * 2. kvm->mm->mmap_sem - find_vma, migrate_vma_pages and helpers, ksm_madvise
+ * 3. kvm->arch.uvmem_lock - protects read/writes to uvmem slots thus acting
+ *			     as sync-points for page-in/out
+ */
+
+/*
+ * Notes on page size
+ *
+ * Currently UV uses 2MB mappings internally, but will issue H_SVM_PAGE_IN
+ * and H_SVM_PAGE_OUT hcalls in PAGE_SIZE(64K) granularity. HV tracks
+ * secure GPAs at 64K page size and maintains one device PFN for each
+ * 64K secure GPA. UV_PAGE_IN and UV_PAGE_OUT calls by HV are also issued
+ * for 64K page at a time.
+ *
+ * HV faulting on secure pages: When HV touches any secure page, it
+ * faults and issues a UV_PAGE_OUT request with 64K page size. Currently
+ * UV splits and remaps the 2MB page if necessary and copies out the
+ * required 64K page contents.
+ *
+ * Shared pages: Whenever guest shares a secure page, UV will split and
+ * remap the 2MB page if required and issue H_SVM_PAGE_IN with 64K page size.
+ *
+ * HV invalidating a page: When a regular page belonging to secure
+ * guest gets unmapped, HV informs UV with UV_PAGE_INVAL of 64K
+ * page size. Using 64K page size is correct here because any non-secure
+ * page will essentially be of 64K page size. Splitting by UV during sharing
+ * and page-out ensures this.
+ *
+ * Page fault handling: When HV handles page fault of a page belonging
+ * to secure guest, it sends that to UV with a 64K UV_PAGE_IN request.
+ * Using 64K size is correct here too as UV would have split the 2MB page
+ * into 64k mappings and would have done page-outs earlier.
+ *
+ * In summary, the current secure pages handling code in HV assumes
+ * 64K page size and in fact fails any page-in/page-out requests of
+ * non-64K size upfront. If and when UV starts supporting multiple
+ * page-sizes, we need to break this assumption.

+	  blocks of physically contiguous memory, then you may need to
+	  increase this value.
+
+	  This config option is actually maximum order plus one. For example,
+	  a value of 11 means that the largest free memory block is 2^10 pages.

+ *
+ * The handle argument of kcov_remote_start() identifies a code section that is
+ * used for coverage collection. A userspace process passes this handle to
+ * KCOV_REMOTE_ENABLE ioctl to make the used kcov device start collecting
+ * coverage for the code section identified by this handle.
+ *
+ * The usage of these annotations in the kernel code is different depending on
+ * the type of the kernel thread whose code is being annotated.
+ *
+ * For global kernel threads that are spawned in a limited number of instances
+ * (e.g. one USB hub_event() worker thread is spawned per USB HCD), each
+ * instance must be assigned a unique 4-byte instance id. The instance id is
+ * then combined with a 1-byte subsystem id to get a handle via
+ * kcov_remote_handle(subsystem_id, instance_id).
+ *
+ * For local kernel threads that are spawned from system calls handler when a
+ * user interacts with some kernel interface (e.g. vhost workers), a handle is
+ * passed from a userspace process as the common_handle field of the
+ * kcov_remote_arg struct (note, that the user must generate a handle by using
+ * kcov_remote_handle() with KCOV_SUBSYSTEM_COMMON as the subsystem id and an
+ * arbitrary 4-byte non-zero number as the instance id). This common handle
+ * then gets saved into the task_struct of the process that issued the
+ * KCOV_REMOTE_ENABLE ioctl. When this proccess issues system calls that spawn
+ * kernel threads, the common handle must be retrived via kcov_common_handle()
+ * and passed to the spawned threads via custom annotations. Those kernel
+ * threads must in turn be annotated with kcov_remote_start(common_handle) and
+ * kcov_remote_stop(). All of the threads that are spawned by the same process
+ * obtain the same handle, hence the name "common".
+ *
+ * See Documentation/dev-tools/kcov.rst for more details.
+ *
+ * Internally, this function looks up the kcov device associated with the
+ * provided handle, allocates an area for coverage collection, and saves the
+ * pointers to kcov and area into the current task_struct to allow coverage to
+ * be collected via __sanitizer_cov_trace_pc()
+ * In turns kcov_remote_stop() clears those pointers from task_struct to stop
+ * collecting coverage and copies all collected coverage into the kcov area.
