+======================================
+HNS3 Performance Monitoring Unit (PMU)
+======================================
+
+HNS3(HiSilicon network system 3) Performance Monitoring Unit (PMU) is an
+End Point device to collect performance statistics of HiSilicon SoC NIC.
+On Hip09, each SICL(Super I/O cluster) has one PMU device.
+
+HNS3 PMU supports collection of performance statistics such as bandwidth,
+latency, packet rate and interrupt rate.
+
+Each HNS3 PMU supports 8 hardware events.
+
+HNS3 PMU driver
+===============
+
+The HNS3 PMU driver registers a perf PMU with the name of its sicl id.::
+
+  /sys/devices/hns3_pmu_sicl_<sicl_id>
+
+PMU driver provides description of available events, filter modes, format,
+identifier and cpumask in sysfs.
+
+The "events" directory describes the event code of all supported events
+shown in perf list.
+
+The "filtermode" directory describes the supported filter modes of each
+event.
+
+The "format" directory describes all formats of the config (events) and
+config1 (filter options) fields of the perf_event_attr structure.
+
+The "identifier" file shows version of PMU hardware device.
+
+The "bdf_min" and "bdf_max" files show the supported bdf range of each
+pmu device.
+
+The "hw_clk_freq" file shows the hardware clock frequency of each pmu
+device.
+
+Example usage of checking event code and subevent code::
+
+  $# cat /sys/devices/hns3_pmu_sicl_0/events/dly_tx_normal_to_mac_time
+  config=0x00204
+  $# cat /sys/devices/hns3_pmu_sicl_0/events/dly_tx_normal_to_mac_packet_num
+  config=0x10204
+
+Each performance statistic has a pair of events to get two values to
+calculate real performance data in userspace.
+
+The bits 0~15 of config (here 0x0204) are the true hardware event code. If
+two events have same value of bits 0~15 of config, that means they are
+event pair. And the bit 16 of config indicates getting counter 0 or
+counter 1 of hardware event.
+
+After getting two values of event pair in usersapce, the formula of
+computation to calculate real performance data is:::
+
+  counter 0 / counter 1
+
+Example usage of checking supported filter mode::
+
+  $# cat /sys/devices/hns3_pmu_sicl_0/filtermode/bw_ssu_rpu_byte_num
+  filter mode supported: global/port/port-tc/func/func-queue/
+
+Example usage of perf::
+
+  $# perf list
+  hns3_pmu_sicl_0/bw_ssu_rpu_byte_num/ [kernel PMU event]
+  hns3_pmu_sicl_0/bw_ssu_rpu_time/     [kernel PMU event]
+  ------------------------------------------
+
+  $# perf stat -g -e hns3_pmu_sicl_0/bw_ssu_rpu_byte_num,global=1/ -e hns3_pmu_sicl_0/bw_ssu_rpu_time,global=1/ -I 1000

+  $# perf stat -g -e hns3_pmu_sicl_0/config=0x00002,global=1/ -e hns3_pmu_sicl_0/config=0x10002,global=1/ -I 1000
+
+
+Filter modes
+--------------
+
+1. global mode
+PMU collect performance statistics for all HNS3 PCIe functions of IO DIE.
+Set the "global" filter option to 1 will enable this mode.
+Example usage of perf::
+
+  $# perf stat -a -e hns3_pmu_sicl_0/config=0x1020F,global=1/ -I 1000
+
+2. port mode
+PMU collect performance statistic of one whole physical port. The port id
+is same as mac id. The "tc" filter option must be set to 0xF in this mode,
+here tc stands for traffic class.
+
+Example usage of perf::
+
+  $# perf stat -a -e hns3_pmu_sicl_0/config=0x1020F,port=0,tc=0xF/ -I 1000
+
+3. port-tc mode
+PMU collect performance statistic of one tc of physical port. The port id
+is same as mac id. The "tc" filter option must be set to 0 ~ 7 in this
+mode.
+Example usage of perf::
+
+  $# perf stat -a -e hns3_pmu_sicl_0/config=0x1020F,port=0,tc=0/ -I 1000
+
+4. func mode
+PMU collect performance statistic of one PF/VF. The function id is BDF of
+PF/VF, its conversion formula::
+
+  func = (bus << 8) + (device << 3) + (function)
+
+for example:
+  BDF         func
+  35:00.0    0x3500
+  35:00.1    0x3501
+  35:01.0    0x3508
+
+In this mode, the "queue" filter option must be set to 0xFFFF.
+Example usage of perf::
+
+  $# perf stat -a -e hns3_pmu_sicl_0/config=0x1020F,bdf=0x3500,queue=0xFFFF/ -I 1000
+
+5. func-queue mode
+PMU collect performance statistic of one queue of PF/VF. The function id
+is BDF of PF/VF, the "queue" filter option must be set to the exact queue
+id of function.
+Example usage of perf::
+
+  $# perf stat -a -e hns3_pmu_sicl_0/config=0x1020F,bdf=0x3500,queue=0/ -I 1000
+
+6. func-intr mode
+PMU collect performance statistic of one interrupt of PF/VF. The function
+id is BDF of PF/VF, the "intr" filter option must be set to the exact
+interrupt id of function.
+Example usage of perf::
+
+  $# perf stat -a -e hns3_pmu_sicl_0/config=0x00301,bdf=0x3500,intr=0/ -I 1000

+======================================
+Chromebook Boot Flow
+======================================
+
+Most recent Chromebooks that use device tree are using the opensource
+depthcharge_ bootloader. Depthcharge_ expects the OS to be packaged as a `FIT
+Image`_ which contains an OS image as well as a collection of device trees. It
+is up to depthcharge_ to pick the right device tree from the `FIT Image`_ and
+provide it to the OS.
+
+The scheme that depthcharge_ uses to pick the device tree takes into account
+three variables:
+
+- Board name, specified at depthcharge_ compile time. This is $(BOARD) below.
+- Board revision number, determined at runtime (perhaps by reading GPIO
+  strappings, perhaps via some other method). This is $(REV) below.
+- SKU number, read from GPIO strappings at boot time. This is $(SKU) below.
+
+For recent Chromebooks, depthcharge_ creates a match list that looks like this:
+
+- google,$(BOARD)-rev$(REV)-sku$(SKU)
+- google,$(BOARD)-rev$(REV)
+- google,$(BOARD)-sku$(SKU)
+- google,$(BOARD)
+
+Note that some older Chromebooks use a slightly different list that may
+not include SKU matching or may prioritize SKU/rev differently.
+
+Note that for some boards there may be extra board-specific logic to inject
+extra compatibles into the list, but this is uncommon.
+
+Depthcharge_ will look through all device trees in the `FIT Image`_ trying to
+find one that matches the most specific compatible. It will then look
+through all device trees in the `FIT Image`_ trying to find the one that
+matches the *second most* specific compatible, etc.
+
+When searching for a device tree, depthcharge_ doesn't care where the
+compatible string falls within a device tree's root compatible string array.
+As an example, if we're on board "lazor", rev 4, SKU 0 and we have two device
+trees:
+
+- "google,lazor-rev5-sku0", "google,lazor-rev4-sku0", "qcom,sc7180"
+- "google,lazor", "qcom,sc7180"
+
+Then depthcharge_ will pick the first device tree even though
+"google,lazor-rev4-sku0" was the second compatible listed in that device tree.
+This is because it is a more specific compatible than "google,lazor".
+
+It should be noted that depthcharge_ does not have any smarts to try to
+match board or SKU revisions that are "close by". That is to say that
+if depthcharge_ knows it's on "rev4" of a board but there is no "rev4"
+device tree then depthcharge_ *won't* look for a "rev3" device tree.
+
+In general when any significant changes are made to a board the board
+revision number is increased even if none of those changes need to
+be reflected in the device tree. Thus it's fairly common to see device
+trees with multiple revisions.
+
+It should be noted that, taking into account the above system that
+depthcharge_ has, the most flexibility is achieved if the device tree
+supporting the newest revision(s) of a board omits the "-rev{REV}"
+compatible strings. When this is done then if you get a new board
+revision and try to run old software on it then we'll at pick the
+newest device tree we know about.

+Pkeys Userspace (PKU) is a feature which can be found on:
+        * Intel server CPUs, Skylake and later
+        * Intel client CPUs, Tiger Lake (11th Gen Core) and later
+        * Future AMD CPUs
+
+Pkeys work by dedicating 4 previously Reserved bits in each page table entry to
+a "protection key", giving 16 possible keys.
+
+Protections for each key are defined with a per-CPU user-accessible register
+(PKRU).  Each of these is a 32-bit register storing two bits (Access Disable
+and Write Disable) for each of 16 keys.
+
+Being a CPU register, PKRU is inherently thread-local, potentially giving each
 thread a different set of protections from every other thread.
 
-There are two new instructions (RDPKRU/WRPKRU) for reading and writing
-to the new register.  The feature is only available in 64-bit mode,
-even though there is theoretically space in the PAE PTEs.  These
-permissions are enforced on data access only and have no effect on
-instruction fetches.

-NXP i.MX System Controller Firmware (SCFW)
---------------------------------------------------------------------
-
-The System Controller Firmware (SCFW) is a low-level system function
-which runs on a dedicated Cortex-M core to provide power, clock, and
-resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
-(QM, QP), and i.MX8QX (QXP, DX).
-
-The AP communicates with the SC using a multi-ported MU module found
-in the LSIO subsystem. The current definition of this MU module provides
-5 remote AP connections to the SC to support up to 5 execution environments
-(TZ, HV, standard Linux, etc.). The SC side of this MU module interfaces
-with the LSIO DSC IP bus. The SC firmware will communicate with this MU
-using the MSI bus.
-
-System Controller Device Node:
-============================================================
-
-The scu node with the following properties shall be under the /firmware/ node.
-
-Required properties:
--------------------
-- compatible:	should be "fsl,imx-scu".
-- mbox-names:	should include "tx0", "tx1", "tx2", "tx3",
-			       "rx0", "rx1", "rx2", "rx3";
-		include "gip3" if want to support general MU interrupt.
-- mboxes:	List of phandle of 4 MU channels for tx, 4 MU channels for
-		rx, and 1 optional MU channel for general interrupt.
-		All MU channels must be in the same MU instance.
-		Cross instances are not allowed. The MU instance can only
-		be one of LSIO MU0~M4 for imx8qxp and imx8qm. Users need
-		to make sure use the one which is not conflict with other
-		execution environments. e.g. ATF.
-		Note:
-		Channel 0 must be "tx0" or "rx0".
-		Channel 1 must be "tx1" or "rx1".
-		Channel 2 must be "tx2" or "rx2".
-		Channel 3 must be "tx3" or "rx3".
-		General interrupt rx channel must be "gip3".
-		e.g.
-		mboxes = <&lsio_mu1 0 0
-			  &lsio_mu1 0 1
-			  &lsio_mu1 0 2
-			  &lsio_mu1 0 3

-			  &lsio_mu1 1 1
-			  &lsio_mu1 1 2
-			  &lsio_mu1 1 3
-			  &lsio_mu1 3 3>;
-		See Documentation/devicetree/bindings/mailbox/fsl,mu.yaml
-		for detailed mailbox binding.
-
-Note: Each mu which supports general interrupt should have an alias correctly
-numbered in "aliases" node.
-e.g.
-aliases {
-	mu1 = &lsio_mu1;
-};

-			each required entry in clock-names
-- clock-names:		Should include entries "xtal_32KHz", "xtal_24MHz"
-
-The clock consumer should specify the desired clock by having the clock
-ID in its "clocks" phandle cell.
-
-See the full list of clock IDs from:
-include/dt-bindings/clock/imx8qxp-clock.h
-
-Pinctrl bindings based on SCU Message Protocol
-------------------------------------------------------------
-
-This binding uses the i.MX common pinctrl binding[3].
-
-Required properties:
-- compatible:		Should be one of:
-			"fsl,imx8qm-iomuxc",
-			"fsl,imx8qxp-iomuxc",
-			"fsl,imx8dxl-iomuxc".
-
-Required properties for Pinctrl sub nodes:
-- fsl,pins:		Each entry consists of 3 integers which represents
-			the mux and config setting for one pin. The first 2
-			integers <pin_id mux_mode> are specified using a
-			PIN_FUNC_ID macro, which can be found in
-			<dt-bindings/pinctrl/pads-imx8qm.h>,
-			<dt-bindings/pinctrl/pads-imx8qxp.h>,
-			<dt-bindings/pinctrl/pads-imx8dxl.h>.
-			The last integer CONFIG is the pad setting value like
-			pull-up on this pin.
-
-			Please refer to i.MX8QXP Reference Manual for detailed
-			CONFIG settings.

+description: |+
+  The Control Backbone (CBB) is comprised of the physical path from an
+  initiator to a target's register configuration space. CBB 1.0 has
+  multiple hierarchical sub-NOCs (Network-on-Chip) and connects various
+  initiators and targets using different bridges like AXIP2P, AXI2APB.
+
+  This driver handles errors due to illegal register accesses reported
+  by the NOCs inside the CBB. NOCs reporting errors are cluster NOCs
+  "AON-NOC, SCE-NOC, RCE-NOC, BPMP-NOC, CV-NOC" and "CBB Central NOC"
+  which is the main NOC.
+
+  By default, the access issuing initiator is informed about the error
+  using SError or Data Abort exception unless the ERD (Error Response
+  Disable) is enabled/set for that initiator. If the ERD is enabled, then
+  SError or Data Abort is masked and the error is reported with interrupt.
+
+  - For CCPLEX (CPU Complex) initiator, the driver sets ERD bit. So, the
+    errors due to illegal accesses from CCPLEX are reported by interrupts.
+    If ERD is not set, then error is reported by SError.
+  - For other initiators, the ERD is disabled. So, the access issuing
+    initiator is informed about the illegal access by Data Abort exception.
+    In addition, an interrupt is also generated to CCPLEX. These initiators
+    include all engines using Cortex-R5 (which is ARMv7 CPU cluster) and
+    engines like TSEC (Security co-processor), NVDEC (NVIDIA Video Decoder
+    engine) etc which can initiate transactions.
+
+  The driver prints relevant debug information like Error Code, Error
+  Description, Master, Address, AXI ID, Cache, Protection, Security Group
+  etc on receiving error notification.

+maintainers:

+
+description: |+
+  The Control Backbone (CBB) is comprised of the physical path from an
+  initiator to a target's register configuration space. CBB 2.0 consists
+  of multiple sub-blocks connected to each other to create a topology.
+  The Tegra234 SoC has different fabrics based on CBB 2.0 architecture
+  which include cluster fabrics BPMP, AON, PSC, SCE, RCE, DCE, FSI and
+  "CBB central fabric".
+
+  In CBB 2.0, each initiator which can issue transactions connects to a
+  Root Master Node (MN) before it connects to any other element of the
+  fabric. Each Root MN contains a Error Monitor (EM) which detects and
+  logs error. Interrupts from various EM blocks are collated by Error
+  Notifier (EN) which is per fabric and presents a single interrupt from
+  fabric to the SoC interrupt controller.
+
+  The driver handles errors from CBB due to illegal register accesses
+  and prints debug information about failed transaction on receiving
+  the interrupt from EN. Debug information includes Error Code, Error
+  Description, MasterID, Fabric, SlaveID, Address, Cache, Protection,
+  Security Group etc on receiving error notification.
+
+  If the Error Response Disable (ERD) is set/enabled for an initiator,
+  then SError or Data abort exception error response is masked and an
+  interrupt is used for reporting errors due to illegal accesses from
+  that initiator. The value returned on read failures is '0xFFFFFFFF'
+  for compatibility with PCIE.

-* Generic Exynos Bus frequency device
-
-The Samsung Exynos SoC has many buses for data transfer between DRAM
-and sub-blocks in SoC. Most Exynos SoCs share the common architecture
-for buses. Generally, each bus of Exynos SoC includes a source clock
-and a power line, which are able to change the clock frequency
-of the bus in runtime. To monitor the usage of each bus in runtime,
-the driver uses the PPMU (Platform Performance Monitoring Unit), which
-is able to measure the current load of sub-blocks.
-
-The Exynos SoC includes the various sub-blocks which have the each AXI bus.
-The each AXI bus has the owned source clock but, has not the only owned
-power line. The power line might be shared among one more sub-blocks.
-So, we can divide into two type of device as the role of each sub-block.
-There are two type of bus devices as following:
-- parent bus device
-- passive bus device
-
-Basically, parent and passive bus device share the same power line.
-The parent bus device can only change the voltage of shared power line
-and the rest bus devices (passive bus device) depend on the decision of
-the parent bus device. If there are three blocks which share the VDD_xxx
-power line, Only one block should be parent device and then the rest blocks
-should depend on the parent device as passive device.
-
-	VDD_xxx |--- A block (parent)
-		|--- B block (passive)
-		|--- C block (passive)
-
-There are a little different composition among Exynos SoC because each Exynos
-SoC has different sub-blocks. Therefore, such difference should be specified
-in devicetree file instead of each device driver. In result, this driver
-is able to support the bus frequency for all Exynos SoCs.
-
-Required properties for all bus devices:
-- compatible: Should be "samsung,exynos-bus".
-- clock-names : the name of clock used by the bus, "bus".
-- clocks : phandles for clock specified in "clock-names" property.
-- operating-points-v2: the OPP table including frequency/voltage information
-  to support DVFS (Dynamic Voltage/Frequency Scaling) feature.
-
-Required properties only for parent bus device:
-- vdd-supply: the regulator to provide the buses with the voltage.
-- devfreq-events: the devfreq-event device to monitor the current utilization
-  of buses.
-
-Required properties only for passive bus device:
-- devfreq: the parent bus device.
-
-Optional properties only for parent bus device:
-- exynos,saturation-ratio: the percentage value which is used to calibrate
-			the performance count against total cycle count.
-
-Optional properties for the interconnect functionality (QoS frequency
-constraints):
-- #interconnect-cells: should be 0.
-- interconnects: as documented in ../interconnect.txt, describes a path at the
-  higher level interconnects used by this interconnect provider.
-  If this interconnect provider is directly linked to a top level interconnect
-  provider the property contains only one phandle. The provider extends
-  the interconnect graph by linking its node to a node registered by provider
-  pointed to by first phandle in the 'interconnects' property.
-
-- samsung,data-clock-ratio: ratio of the data throughput in B/s to minimum data
-   clock frequency in Hz, default value is 8 when this property is missing.
-
-Detailed correlation between sub-blocks and power line according to Exynos SoC:
-- In case of Exynos3250, there are two power line as following:
-	VDD_MIF |--- DMC
-
-	VDD_INT |--- LEFTBUS (parent device)

+title: NXP i.MX System Controller Firmware (SCFW)
+
+maintainers:
+  - Dong Aisheng <aisheng.dong@nxp.com>
+
+description:
+  The System Controller Firmware (SCFW) is a low-level system function
+  which runs on a dedicated Cortex-M core to provide power, clock, and
+  resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
+  (QM, QP), and i.MX8QX (QXP, DX).
+  The AP communicates with the SC using a multi-ported MU module found
+  in the LSIO subsystem. The current definition of this MU module provides
+  5 remote AP connections to the SC to support up to 5 execution environments
+  (TZ, HV, standard Linux, etc.). The SC side of this MU module interfaces
+  with the LSIO DSC IP bus. The SC firmware will communicate with this MU
+  using the MSI bus.

+      channels is 1 TX and 1 RX channels if MU instance is "fsl,imx8-mu-scu"
+      compatible, 4 TX and 4 RX channels otherwise. All MU channels must be
+      within the same MU instance. Cross instances are not allowed. The MU
+      instance can only be one of LSIO MU0~M4 for imx8qxp and imx8qm. Users
+      need to ensure that one is used that does not conflict with other
+      execution environments such as ATF.

+
+description: |
+  The Samsung Exynos SoC has many buses for data transfer between DRAM and
+  sub-blocks in SoC. Most Exynos SoCs share the common architecture for buses.
+  Generally, each bus of Exynos SoC includes a source clock and a power line,
+  which are able to change the clock frequency of the bus in runtime. To
+  monitor the usage of each bus in runtime, the driver uses the PPMU (Platform
+  Performance Monitoring Unit), which is able to measure the current load of
+  sub-blocks.
+
+  The Exynos SoC includes the various sub-blocks which have the each AXI bus.
+  The each AXI bus has the owned source clock but, has not the only owned power
+  line. The power line might be shared among one more sub-blocks.  So, we can
+  divide into two type of device as the role of each sub-block.  There are two
+  type of bus devices as following::
+   - parent bus device
+   - passive bus device
+
+  Basically, parent and passive bus device share the same power line.  The
+  parent bus device can only change the voltage of shared power line and the
+  rest bus devices (passive bus device) depend on the decision of the parent
+  bus device. If there are three blocks which share the VDD_xxx power line,
+  Only one block should be parent device and then the rest blocks should depend
+  on the parent device as passive device.
+
+    VDD_xxx |--- A block (parent)
+      |--- B block (passive)
+      |--- C block (passive)
+
+  There are a little different composition among Exynos SoC because each Exynos
+  SoC has different sub-blocks. Therefore, such difference should be specified
+  in devicetree file instead of each device driver. In result, this driver is
+  able to support the bus frequency for all Exynos SoCs.
+
+  Detailed correlation between sub-blocks and power line according
+  to Exynos SoC::
+   - In case of Exynos3250, there are two power line as following::

-Bindings for the Generic PWM Regulator
-======================================
-
-Currently supports 2 modes of operation:
-
-Voltage Table:		When in this mode, a voltage table (See below) of
-			predefined voltage <=> duty-cycle values must be
-			provided via DT. Limitations are that the regulator can
-			only operate at the voltages supplied in the table.
-			Intermediary duty-cycle values which would normally
-			allow finer grained voltage selection are ignored and
-			rendered useless.  Although more control is given to
-			the user if the assumptions made in continuous-voltage
-			mode do not reign true.
-
-Continuous Voltage:	This mode uses the regulator's maximum and minimum
-			supplied voltages specified in the
-			regulator-{min,max}-microvolt properties to calculate
-			appropriate duty-cycle values.  This allows for a much
-			more fine grained solution when compared with
-			voltage-table mode above.  This solution does make an
-			assumption that a %50 duty-cycle value will cause the
-			regulator voltage to run at half way between the
-			supplied max_uV and min_uV values.
-
-Required properties:
---------------------
-- compatible:		Should be "pwm-regulator"
-
-- pwms:			PWM specification (See: ../pwm/pwm.txt)
-
-Only required for Voltage Table Mode:
-- voltage-table: 	Voltage and Duty-Cycle table consisting of 2 cells
-			    First cell is voltage in microvolts (uV)
-			    Second cell is duty-cycle in percent (%)
-
-Optional properties for Continuous mode:
-- pwm-dutycycle-unit:	Integer value encoding the duty cycle unit. If not
-			defined, <100> is assumed, meaning that
-			pwm-dutycycle-range contains values expressed in
-			percent.
-
-- pwm-dutycycle-range:	Should contain 2 entries. The first entry is encoding
-			the dutycycle for regulator-min-microvolt and the
-			second one the dutycycle for regulator-max-microvolt.
-			Duty cycle values are expressed in pwm-dutycycle-unit.
-			If not defined, <0 100> is assumed.
-
-NB: To be clear, if voltage-table is provided, then the device will be used
-in Voltage Table Mode.  If no voltage-table is provided, then the device will
-be used in Continuous Voltage Mode.
-
-Optional properties:
---------------------
-- enable-gpios:		GPIO to use to enable/disable the regulator
-
-Any property defined as part of the core regulator binding can also be used.
-(See: ../regulator/regulator.txt)
-
-Continuous Voltage With Enable GPIO Example:
-	pwm_regulator {
-		compatible = "pwm-regulator";
-		pwms = <&pwm1 0 8448 0>;
-		enable-gpios = <&gpio0 23 GPIO_ACTIVE_HIGH>;
-		regulator-min-microvolt = <1016000>;
-		regulator-max-microvolt = <1114000>;
-		regulator-name = "vdd_logic";
-		/* unit == per-mille */
-		pwm-dutycycle-unit = <1000>;
-		/*
-		 * Inverted PWM logic, and the duty cycle range is limited
-		 * to 30%-70%.
-		 */
-		pwm-dutycycle-range = <700 300>; /* */
-	};
-
-Voltage Table Example:
-	pwm_regulator {
-		compatible = "pwm-regulator";
-		pwms = <&pwm1 0 8448 0>;
-		regulator-min-microvolt = <1016000>;
-		regulator-max-microvolt = <1114000>;
-		regulator-name = "vdd_logic";
-
-			      /* Voltage Duty-Cycle */
-		voltage-table = <1114000 0>,
-				<1095000 10>,
-				<1076000 20>,
-				<1056000 30>,
-				<1036000 40>,
-				<1016000 50>;
-	};

-The content of each sub-node is defined by the standard binding for regulators -
-see regulator.txt - with additional custom properties described below:
-
-- regulator-initial-mode:
-	Usage: optional
-	Value type: <u32>
-	Description: 2 = Set initial mode to auto mode (automatically select
-		    between HPM and LPM); not available on boost type
-		    regulators.
-
-		    1 = Set initial mode to high power mode (HPM), also referred
-		    to as NPM. HPM consumes more ground current than LPM, but
-		    it can source significantly higher load current. HPM is not
-		    available on boost type regulators. For voltage switch type
-		    regulators, HPM implies that over current protection and
-		    soft start are active all the time.
-
-		    0 = Set initial mode to low power mode (LPM).
-
-- qcom,ocp-max-retries:
-	Usage: optional
-	Value type: <u32>
-	Description: Maximum number of times to try toggling a voltage switch
-		     off and back on as a result of consecutive over current
-		     events.
-
-- qcom,ocp-retry-delay:
-	Usage: optional
-	Value type: <u32>
-	Description: Time to delay in milliseconds between each voltage switch
-		     toggle after an over current event takes place.
-
-- qcom,pin-ctrl-enable:
-	Usage: optional
-	Value type: <u32>
-	Description: Bit mask specifying which hardware pins should be used to
-		     enable the regulator, if any; supported bits are:
-			0 = ignore all hardware enable signals
-			BIT(0) = follow HW0_EN signal
-			BIT(1) = follow HW1_EN signal
-			BIT(2) = follow HW2_EN signal
-			BIT(3) = follow HW3_EN signal
-
-- qcom,pin-ctrl-hpm:
-	Usage: optional
-	Value type: <u32>
-	Description: Bit mask specifying which hardware pins should be used to
-		     force the regulator into high power mode, if any;
-		     supported bits are:
-			0 = ignore all hardware enable signals
-			BIT(0) = follow HW0_EN signal
-			BIT(1) = follow HW1_EN signal
-			BIT(2) = follow HW2_EN signal

-		     switch type regulators; supported values are:
-			0 = 0.05 uA
-			1 = 0.25 uA
-			2 = 0.55 uA
-			3 = 0.75 uA
-
-- qcom,saw-slave:
-	Usage: optional
-	Value type: <boo>
-	Description: SAW controlled gang slave. Will not be configured.
-
-- qcom,saw-leader:
-	Usage: optional
-	Value type: <boo>
-	Description: SAW controlled gang leader. Will be configured as
-		     SAW regulator.

-BCM2835 PM (Power domains, watchdog)
-
-The PM block controls power domains and some reset lines, and includes
-a watchdog timer.  This binding supersedes the brcm,bcm2835-pm-wdt
-binding which covered some of PM's register range and functionality.
-
-Required properties:
-
-- compatible:		Should be "brcm,bcm2835-pm"
-- reg:			Specifies base physical address and size of the two
-			  register ranges ("PM" and "ASYNC_BRIDGE" in that
-			  order)
-- clocks:		a) v3d: The V3D clock from CPRMAN
-			b) peri_image: The PERI_IMAGE clock from CPRMAN
-			c) h264: The H264 clock from CPRMAN
-			d) isp: The ISP clock from CPRMAN
-- #reset-cells: 	Should be 1.  This property follows the reset controller
-			  bindings[1].
-- #power-domain-cells:	Should be 1.  This property follows the power domain
-			  bindings[2].
-
-Optional properties:
-
-- timeout-sec:		Contains the watchdog timeout in seconds
-- system-power-controller: Whether the watchdog is controlling the
-    system power.  This node follows the power controller bindings[3].

+-----------
+
+LT7182S is a Dual Channel 6A, 20V PolyPhase Step-Down Silent Switcher with
+Digital Power System Management support.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.
+
+Example: the following commands will load the driver for a LT7182S
+at address 0x4f on I2C bus #4::
+
+    # modprobe lt7182s
+    # echo lt7182s 0x4f > /sys/bus/i2c/devices/i2c-4/new_device
+
+It can also be instantiated by declaring an entry in device tree.

 Driver development
 ==================
 
-DSA switch drivers need to implement a dsa_switch_ops structure which will
+DSA switch drivers need to implement a ``dsa_switch_ops`` structure which will
 contain the various members described below.
 
-``register_switch_driver()`` registers this dsa_switch_ops in its internal list
-of drivers to probe for. ``unregister_switch_driver()`` does the exact opposite.
+Probing, registration and device lifetime
+-----------------------------------------
 
-Unless requested differently by setting the priv_size member accordingly, DSA
-does not allocate any driver private context space.
+DSA switches are regular ``device`` structures on buses (be they platform, SPI,
+I2C, MDIO or otherwise). The DSA framework is not involved in their probing
+with the device core.
+
+Switch registration from the perspective of a driver means passing a valid
+``struct dsa_switch`` pointer to ``dsa_register_switch()``, usually from the
+switch driver's probing function. The following members must be valid in the
+provided structure:
+
+- ``ds->dev``: will be used to parse the switch's OF node or platform data.
+
+- ``ds->num_ports``: will be used to create the port list for this switch, and
+  to validate the port indices provided in the OF node.
+
+- ``ds->ops``: a pointer to the ``dsa_switch_ops`` structure holding the DSA
+  method implementations.
+
+- ``ds->priv``: backpointer to a driver-private data structure which can be
+  retrieved in all further DSA method callbacks.
+
+In addition, the following flags in the ``dsa_switch`` structure may optionally
+be configured to obtain driver-specific behavior from the DSA core. Their
+behavior when set is documented through comments in ``include/net/dsa.h``.
+
+- ``ds->vlan_filtering_is_global``
+
+- ``ds->needs_standalone_vlan_filtering``
+
+- ``ds->configure_vlan_while_not_filtering``
+
+- ``ds->untag_bridge_pvid``
+
+- ``ds->assisted_learning_on_cpu_port``
+
+- ``ds->mtu_enforcement_ingress``
+
+- ``ds->fdb_isolation``
+
+Internally, DSA keeps an array of switch trees (group of switches) global to
+the kernel, and attaches a ``dsa_switch`` structure to a tree on registration.
+The tree ID to which the switch is attached is determined by the first u32
+number of the ``dsa,member`` property of the switch's OF node (0 if missing).
+The switch ID within the tree is determined by the second u32 number of the
+same OF property (0 if missing). Registering multiple switches with the same
+switch ID and tree ID is illegal and will cause an error. Using platform data,
+a single switch and a single switch tree is permitted.
+
+In case of a tree with multiple switches, probing takes place asymmetrically.
+The first N-1 callers of ``dsa_register_switch()`` only add their ports to the
+port list of the tree (``dst->ports``), each port having a backpointer to its
+associated switch (``dp->ds``). Then, these switches exit their
+``dsa_register_switch()`` call early, because ``dsa_tree_setup_routing_table()``
+has determined that the tree is not yet complete (not all ports referenced by
+DSA links are present in the tree's port list). The tree becomes complete when
+the last switch calls ``dsa_register_switch()``, and this triggers the effective
+continuation of initialization (including the call to ``ds->ops->setup()``) for
+all switches within that tree, all as part of the calling context of the last
+switch's probe function.
+
+The opposite of registration takes place when calling ``dsa_unregister_switch()``,
+which removes a switch's ports from the port list of the tree. The entire tree
+is torn down when the first switch unregisters.
+
+It is mandatory for DSA switch drivers to implement the ``shutdown()`` callback
+of their respective bus, and call ``dsa_switch_shutdown()`` from it (a minimal
+version of the full teardown performed by ``dsa_unregister_switch()``).
+The reason is that DSA keeps a reference on the master net device, and if the
+driver for the master device decides to unbind on shutdown, DSA's reference
+will block that operation from finalizing.
+

+Address databases
+-----------------
+
+Switching hardware is expected to have a table for FDB entries, however not all
+of them are active at the same time. An address database is the subset (partition)
+of FDB entries that is active (can be matched by address learning on RX, or FDB
+lookup on TX) depending on the state of the port. An address database may
+occasionally be called "FID" (Filtering ID) in this document, although the
+underlying implementation may choose whatever is available to the hardware.
+
+For example, all ports that belong to a VLAN-unaware bridge (which is
+*currently* VLAN-unaware) are expected to learn source addresses in the
+database associated by the driver with that bridge (and not with other
+VLAN-unaware bridges). During forwarding and FDB lookup, a packet received on a
+VLAN-unaware bridge port should be able to find a VLAN-unaware FDB entry having
+the same MAC DA as the packet, which is present on another port member of the
+same bridge. At the same time, the FDB lookup process must be able to not find
+an FDB entry having the same MAC DA as the packet, if that entry points towards
+a port which is a member of a different VLAN-unaware bridge (and is therefore
+associated with a different address database).
+
+Similarly, each VLAN of each offloaded VLAN-aware bridge should have an
+associated address database, which is shared by all ports which are members of
+that VLAN, but not shared by ports belonging to different bridges that are
+members of the same VID.
+
+In this context, a VLAN-unaware database means that all packets are expected to
+match on it irrespective of VLAN ID (only MAC address lookup), whereas a
+VLAN-aware database means that packets are supposed to match based on the VLAN
+ID from the classified 802.1Q header (or the pvid if untagged).
+
+At the bridge layer, VLAN-unaware FDB entries have the special VID value of 0,
+whereas VLAN-aware FDB entries have non-zero VID values. Note that a
+VLAN-unaware bridge may have VLAN-aware (non-zero VID) FDB entries, and a
+VLAN-aware bridge may have VLAN-unaware FDB entries. As in hardware, the
+software bridge keeps separate address databases, and offloads to hardware the
+FDB entries belonging to these databases, through switchdev, asynchronously
+relative to the moment when the databases become active or inactive.
+
+When a user port operates in standalone mode, its driver should configure it to
+use a separate database called a port private database. This is different from
+the databases described above, and should impede operation as standalone port
+(packet in, packet out to the CPU port) as little as possible. For example,
+on ingress, it should not attempt to learn the MAC SA of ingress traffic, since
+learning is a bridging layer service and this is a standalone port, therefore
+it would consume useless space. With no address learning, the port private
+database should be empty in a naive implementation, and in this case, all
+received packets should be trivially flooded to the CPU port.
+
+DSA (cascade) and CPU ports are also called "shared" ports because they service
+multiple address databases, and the database that a packet should be associated
+to is usually embedded in the DSA tag. This means that the CPU port may
+simultaneously transport packets coming from a standalone port (which were
+classified by hardware in one address database), and from a bridge port (which
+were classified to a different address database).
+
+Switch drivers which satisfy certain criteria are able to optimize the naive
+configuration by removing the CPU port from the flooding domain of the switch,
+and just program the hardware with FDB entries pointing towards the CPU port
+for which it is known that software is interested in those MAC addresses.
+Packets which do not match a known FDB entry will not be delivered to the CPU,
+which will save CPU cycles required for creating an skb just to drop it.
+
+DSA is able to perform host address filtering for the following kinds of
+addresses:
+
+- Primary unicast MAC addresses of ports (``dev->dev_addr``). These are
+  associated with the port private database of the respective user port,
+  and the driver is notified to install them through ``port_fdb_add`` towards
+  the CPU port.
+
+- Secondary unicast and multicast MAC addresses of ports (addresses added
+  through ``dev_uc_add()`` and ``dev_mc_add()``). These are also associated
+  with the port private database of the respective user port.
+
+- Local/permanent bridge FDB entries (``BR_FDB_LOCAL``). These are the MAC
+  addresses of the bridge ports, for which packets must be terminated locally
+  and not forwarded. They are associated with the address database for that
+  bridge.
+
+- Static bridge FDB entries installed towards foreign (non-DSA) interfaces
+  present in the same bridge as some DSA switch ports. These are also
+  associated with the address database for that bridge.
+
+- Dynamically learned FDB entries on foreign interfaces present in the same
+  bridge as some DSA switch ports, only if ``ds->assisted_learning_on_cpu_port``
+  is set to true by the driver. These are associated with the address database
+  for that bridge.
+
+For various operations detailed below, DSA provides a ``dsa_db`` structure
+which can be of the following types:
+
+- ``DSA_DB_PORT``: the FDB (or MDB) entry to be installed or deleted belongs to
+  the port private database of user port ``db->dp``.
+- ``DSA_DB_BRIDGE``: the entry belongs to one of the address databases of bridge
+  ``db->bridge``. Separation between the VLAN-unaware database and the per-VID
+  databases of this bridge is expected to be done by the driver.
+- ``DSA_DB_LAG``: the entry belongs to the address database of LAG ``db->lag``.
+  Note: ``DSA_DB_LAG`` is currently unused and may be removed in the future.
+
+The drivers which act upon the ``dsa_db`` argument in ``port_fdb_add``,
+``port_mdb_add`` etc should declare ``ds->fdb_isolation`` as true.
+
+DSA associates each offloaded bridge and each offloaded LAG with a one-based ID
+(``struct dsa_bridge :: num``, ``struct dsa_lag :: id``) for the purposes of
+refcounting addresses on shared ports. Drivers may piggyback on DSA's numbering
+scheme (the ID is readable through ``db->bridge.num`` and ``db->lag.id`` or may
+implement their own.
+
+Only the drivers which declare support for FDB isolation are notified of FDB
+entries on the CPU port belonging to ``DSA_DB_PORT`` databases.
+For compatibility/legacy reasons, ``DSA_DB_BRIDGE`` addresses are notified to
+drivers even if they do not support FDB isolation. However, ``db->bridge.num``
+and ``db->lag.id`` are always set to 0 in that case (to denote the lack of
+isolation, for refcounting purposes).
+
+Note that it is not mandatory for a switch driver to implement physically
+separate address databases for each standalone user port. Since FDB entries in
+the port private databases will always point to the CPU port, there is no risk
+for incorrect forwarding decisions. In this case, all standalone ports may
+share the same database, but the reference counting of host-filtered addresses
+(not deleting the FDB entry for a port's MAC address if it's still in use by
+another port) becomes the responsibility of the driver, because DSA is unaware
+that the port databases are in fact shared. This can be achieved by calling
+``dsa_fdb_present_in_other_db()`` and ``dsa_mdb_present_in_other_db()``.
+The down side is that the RX filtering lists of each user port are in fact
+shared, which means that user port A may accept a packet with a MAC DA it
+shouldn't have, only because that MAC address was in the RX filtering list of
+user port B. These packets will still be dropped in software, however.
+
 Bridge layer
 ------------
 
+Offloading the bridge forwarding plane is optional and handled by the methods
+below. They may be absent, return -EOPNOTSUPP, or ``ds->max_num_bridges`` may
+be non-zero and exceeded, and in this case, joining a bridge port is still
+possible, but the packet forwarding will take place in software, and the ports
+under a software bridge must remain configured in the same way as for
+standalone operation, i.e. have all bridging service functions (address
+learning etc) disabled, and send all received packets to the CPU port only.
+
+Concretely, a port starts offloading the forwarding plane of a bridge once it
+returns success to the ``port_bridge_join`` method, and stops doing so after
+``port_bridge_leave`` has been called. Offloading the bridge means autonomously
+learning FDB entries in accordance with the software bridge port's state, and
+autonomously forwarding (or flooding) received packets without CPU intervention.
+This is optional even when offloading a bridge port. Tagging protocol drivers
+are expected to call ``dsa_default_offload_fwd_mark(skb)`` for packets which
+have already been autonomously forwarded in the forwarding domain of the
+ingress switch port. DSA, through ``dsa_port_devlink_setup()``, considers all
+switch ports part of the same tree ID to be part of the same bridge forwarding
+domain (capable of autonomous forwarding to each other).
+
+Offloading the TX forwarding process of a bridge is a distinct concept from
+simply offloading its forwarding plane, and refers to the ability of certain
+driver and tag protocol combinations to transmit a single skb coming from the
+bridge device's transmit function to potentially multiple egress ports (and
+thereby avoid its cloning in software).
+
+Packets for which the bridge requests this behavior are called data plane
+packets and have ``skb->offload_fwd_mark`` set to true in the tag protocol
+driver's ``xmit`` function. Data plane packets are subject to FDB lookup,
+hardware learning on the CPU port, and do not override the port STP state.
+Additionally, replication of data plane packets (multicast, flooding) is
+handled in hardware and the bridge driver will transmit a single skb for each
+packet that may or may not need replication.
+
+When the TX forwarding offload is enabled, the tag protocol driver is
+responsible to inject packets into the data plane of the hardware towards the
+correct bridging domain (FID) that the port is a part of. The port may be
+VLAN-unaware, and in this case the FID must be equal to the FID used by the
+driver for its VLAN-unaware address database associated with that bridge.
+Alternatively, the bridge may be VLAN-aware, and in that case, it is guaranteed
+that the packet is also VLAN-tagged with the VLAN ID that the bridge processed
+this packet in. It is the responsibility of the hardware to untag the VID on
+the egress-untagged ports, or keep the tag on the egress-tagged ones.

-	 * physical address space. So for the ID map, use an extended virtual
-	 * range in that case, and configure an additional translation level
-	 * if needed.
+	 * The ID map carries a 1:1 mapping of the physical address range
+	 * covered by the loaded image, which could be anywhere in DRAM. This
+	 * means that the required size of the VA (== PA) space is decided at
+	 * boot time, and could be more than the configured size of the VA
+	 * space for ordinary kernel and user space mappings.
+	 *
+	 * There are three cases to consider here:
+	 * - 39 <= VA_BITS < 48, and the ID map needs up to 48 VA bits to cover
+	 *   the placement of the image. In this case, we configure one extra
+	 *   level of translation on the fly for the ID map only. (This case
+	 *   also covers 42-bit VA/52-bit PA on 64k pages).
 	 *
-	 * Calculate the maximum allowed value for TCR_EL1.T0SZ so that the
-	 * entire ID map region can be mapped. As T0SZ == (64 - #bits used),
-	 * this number conveniently equals the number of leading zeroes in
-	 * the physical address of __idmap_text_end.
+	 * - VA_BITS == 48, and the ID map needs more than 48 VA bits. This can
+	 *   only happen when using 64k pages, in which case we need to extend
+	 *   the root level table rather than add a level. Note that we can
+	 *   treat this case as 'always extended' as long as we take care not
+	 *   to program an unsupported T0SZ value into the TCR register.

+	 *
+	 *    The "user -> user" attack scenario is mitigated by RSB filling.
+	 *
+	 * 2) Poisoned RSB entry
+	 *
+	 *    If the 'next' in-kernel return stack is shorter than 'prev',
+	 *    'next' could be tricked into speculating with a user-poisoned RSB
+	 *    entry.
+	 *
+	 *    The "user -> kernel" attack scenario is mitigated by SMEP and
+	 *    eIBRS.
+	 *
+	 *    The "user -> user" scenario, also known as SpectreBHB, requires

+/*
+ * In order to handle platform originated SCMI SystemPower requests (like
+ * shutdowns or cold/warm resets) we register an SCMI Notification notifier
+ * block to react when such SCMI SystemPower events are emitted by platform.
+ *
+ * Once such a notification is received we act accordingly to perform the
+ * required system transition depending on the kind of request.
+ *
+ * Graceful requests are routed to userspace through the same API methods
+ * (orderly_poweroff/reboot()) used by ACPI when handling ACPI Shutdown bus
+ * events.
+ *
+ * Direct forceful requests are not supported since are not meant to be sent
+ * by the SCMI platform to an OSPM like Linux.
+ *
+ * Additionally, graceful request notifications can carry an optional timeout
+ * field stating the maximum amount of time allowed by the platform for
+ * completion after which they are converted to forceful ones: the assumption
+ * here is that even graceful requests can be upper-bound by a maximum final
+ * timeout strictly enforced by the platform itself which can ultimately cut
+ * the power off at will anytime; in order to avoid such extreme scenario, we
+ * track progress of graceful requests through the means of a reboot notifier
+ * converting timed-out graceful requests to forceful ones, so at least we
+ * try to perform a clean sync and shutdown/restart before the power is cut.
+ *
+ * Given the peculiar nature of SCMI SystemPower protocol, that is being in
+ * charge of triggering system wide shutdown/reboot events, there should be
+ * only one SCMI platform actively emitting SystemPower events.
+ * For this reason the SCMI core takes care to enforce the creation of one
+ * single unique device associated to the SCMI System Power protocol; no matter
+ * how many SCMI platforms are defined on the system, only one can be designated
+ * to support System Power: as a consequence this driver will never be probed
+ * more than once.
+ *
+ * For similar reasons as soon as the first valid SystemPower is received by
+ * this driver and the shutdown/reboot is started, any further notification
+ * possibly emitted by the platform will be ignored.

+ * Each hardware event contains two registers (counter and ext_counter) for
+ * bandwidth, packet rate, latency and interrupt rate. These two registers will
+ * be triggered to run at the same when a hardware event is enabled. The meaning
+ * of counter and ext_counter of different event type are different, their
+ * meaning show as follow:
+ *
+ * +----------------+------------------+---------------+
+ * |   event type   |     counter      |  ext_counter  |
+ * +----------------+------------------+---------------+
+ * | bandwidth      | byte number      | cycle number  |
+ * +----------------+------------------+---------------+
+ * | packet rate    | packet number    | cycle number  |
+ * +----------------+------------------+---------------+
+ * | latency        | cycle number     | packet number |
+ * +----------------+------------------+---------------+
+ * | interrupt rate | interrupt number | cycle number  |
+ * +----------------+------------------+---------------+
+ *
+ * The cycle number indicates increment of counter of hardware timer, the
+ * frequency of hardware timer can be read from hw_clk_freq file.
+ *
+ * Performance of each hardware event is calculated by: counter / ext_counter.
+ *
+ * Since processing of data is preferred to be done in userspace, we expose
+ * ext_counter as a separate event for userspace and use bit 16 to indicate it.
+ * For example, event 0x00001 and 0x10001 are actually one event for hardware
+ * because bit 0-15 are same. If the bit 16 of one event is 0 means to read
+ * counter register, otherwise means to read ext_counter register.

+ * - The hardware doesn't support ON = 0, so the active part of a period doesn't

+ * - The hardware could support inverted polarity (with a similar limitation as
+ *   for normal: the last clock tick is always inactive).
+ * - The hardware emits a constant low output when disabled.
+ * - A request for .duty_cycle = 0 results in an output wave with one active
+ *   clock tick per period. This should better use the disabled state.
+ * - The driver only implements setting the relative duty cycle.

+	  The Smart Voltage Scaling(SVS) engine is a piece of hardware
+	  which has several controllers(banks) for calculating suitable
+	  voltage to different power domains(CPU/GPU/CCI) according to
+	  chip process corner, temperatures and other factors. Then DVFS
+	  driver could apply SVS bank voltage to PMIC/Buck.
