-UniPhier outer cache controller
-
-UniPhier SoCs are integrated with a full-custom outer cache controller system.
-All of them have a level 2 cache controller, and some have a level 3 cache
-controller as well.
-
-Required properties:
-- compatible: should be "socionext,uniphier-system-cache"
-- reg: offsets and lengths of the register sets for the device. It should
- contain 3 regions: control register, revision register, operation register,
- in this order.
-- cache-unified: specifies the cache is a unified cache.
-- cache-size: specifies the size in bytes of the cache
-- cache-sets: specifies the number of associativity sets of the cache
-- cache-line-size: specifies the line size in bytes
-- cache-level: specifies the level in the cache hierarchy. The value should
- be 2 for L2 cache, 3 for L3 cache, etc.
-
-Optional properties:
-- next-level-cache: phandle to the next level cache if present. The next level
- cache should be also compatible with "socionext,uniphier-system-cache".
-
-The L2 cache must exist to use the L3 cache; the cache hierarchy must be
-indicated correctly with "next-level-cache" properties.
-
-Example 1 (system with L2):
- l2: l2-cache@500c0000 {
- compatible = "socionext,uniphier-system-cache";
- reg = <0x500c0000 0x2000>, <0x503c0100 0x4>,
- <0x506c0000 0x400>;
- cache-unified;
- cache-size = <0x80000>;
- cache-sets = <256>;
- cache-line-size = <128>;
- cache-level = <2>;
- };
-
-Example 2 (system with L2 and L3):
- l2: l2-cache@500c0000 {
- compatible = "socionext,uniphier-system-cache";
- reg = <0x500c0000 0x2000>, <0x503c0100 0x8>,

-- #address-cells: should be 2. The first cell is the bank number (chip select).
- The second cell is the address offset within the bank.

-- ranges: should provide a proper address translation from the System Bus to

-USB Connector
-=============
-
-A USB connector node represents a physical USB connector. It should be
-a child of a USB interface controller.
-
-Required properties:
-- compatible: describes type of the connector, must be one of:
- "usb-a-connector",
- "usb-b-connector",
- "usb-c-connector".
-
-Optional properties:
-- label: symbolic name for the connector,
-- type: size of the connector, should be specified in case of USB-A, USB-B
- non-fullsize connectors: "mini", "micro".
-- self-powered: Set this property if the usb device that has its own power
- source.
-
-Optional properties for usb-b-connector:
-- id-gpios: an input gpio for USB ID pin.
-- vbus-gpios: an input gpio for USB VBUS pin, used to detect presence of
- VBUS 5V.
- see gpio/gpio.txt.
-- vbus-supply: a phandle to the regulator for USB VBUS if needed when host
- mode or dual role mode is supported.
- Particularly, if use an output GPIO to control a VBUS regulator, should
- model it as a regulator.
- see regulator/fixed-regulator.yaml
-- pinctrl-names : a pinctrl state named "default" is optional
-- pinctrl-0 : pin control group
- see pinctrl/pinctrl-bindings.txt
-
-Optional properties for usb-c-connector:
-- power-role: should be one of "source", "sink" or "dual"(DRP) if typec
- connector has power support.
-- try-power-role: preferred power role if "dual"(DRP) can support Try.SNK
- or Try.SRC, should be "sink" for Try.SNK or "source" for Try.SRC.
-- data-role: should be one of "host", "device", "dual"(DRD) if typec
- connector supports USB data.
-
-Required properties for usb-c-connector with power delivery support:
-- source-pdos: An array of u32 with each entry providing supported power
- source data object(PDO), the detailed bit definitions of PDO can be found
- in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.2
- Source_Capabilities Message, the order of each entry(PDO) should follow
- the PD spec chapter 6.4.1. Required for power source and power dual role.
- User can specify the source PDO array via PDO_FIXED/BATT/VAR/PPS_APDO()
- defined in dt-bindings/usb/pd.h.
-- sink-pdos: An array of u32 with each entry providing supported power
- sink data object(PDO), the detailed bit definitions of PDO can be found
- in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.3
- Sink Capabilities Message, the order of each entry(PDO) should follow
- the PD spec chapter 6.4.1. Required for power sink and power dual role.
- User can specify the sink PDO array via PDO_FIXED/BATT/VAR/PPS_APDO() defined
- in dt-bindings/usb/pd.h.
-- op-sink-microwatt: Sink required operating power in microwatt, if source
- can't offer the power, Capability Mismatch is set. Required for power
- sink and power dual role.
-
-Required nodes:
-- any data bus to the connector should be modeled using the OF graph bindings
- specified in bindings/graph.txt, unless the bus is between parent node and
- the connector. Since single connector can have multiple data buses every bus
- has assigned OF graph port number as follows:
- 0: High Speed (HS), present in all connectors,
- 1: Super Speed (SS), present in SS capable connectors,
- 2: Sideband use (SBU), present in USB-C.
-
-Examples
---------
-
-1. Micro-USB connector with HS lines routed via controller (MUIC):
-
-muic-max77843@66 {

- label = "micro-USB";
- type = "micro";
- };
-};
-
-2. USB-C connector attached to CC controller (s2mm005), HS lines routed
-to companion PMIC (max77865), SS lines to USB3 PHY and SBU to DisplayPort.
-DisplayPort video lines are routed to the connector via SS mux in USB3 PHY.
-
-ccic: s2mm005@33 {
- ...
- usb_con: connector {
- compatible = "usb-c-connector";
- label = "USB-C";
-

- };
- };
- };
- };
-};
-
-3. USB-C connector attached to a typec port controller(ptn5110), which has
-power delivery support and enables drp.
-
-typec: ptn5110@50 {
- ...
- usb_con: connector {

-Vivante GPU core devices
-========================
-
-Required properties:
-- compatible: Should be "vivante,gc"
- A more specific compatible is not needed, as the cores contain chip
- identification registers at fixed locations, which provide all the
- necessary information to the driver.
-- reg: should be register base and length as documented in the
- datasheet
-- interrupts: Should contain the cores interrupt line
-- clocks: should contain one clock for entry in clock-names
- see Documentation/devicetree/bindings/clock/clock-bindings.txt
-- clock-names:
- - "bus": AXI/master interface clock
- - "reg": AHB/slave interface clock
- (only required if GPU can gate slave interface independently)
- - "core": GPU core clock
- - "shader": Shader clock (only required if GPU has feature PIPE_3D)
-
-Optional properties:
-- power-domains: a power domain consumer specifier according to
- Documentation/devicetree/bindings/power/power_domain.txt
-
-example:
-
-gpu_3d: gpu@130000 {
- compatible = "vivante,gc";
- reg = <0x00130000 0x4000>;
- interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&clks IMX6QDL_CLK_GPU3D_AXI>,
- <&clks IMX6QDL_CLK_GPU3D_CORE>,
- <&clks IMX6QDL_CLK_GPU3D_SHADER>;
- clock-names = "bus", "core", "shader";
- power-domains = <&gpc 1>;
-};

-UniPhier GPIO controller
-
-Required properties:
-- compatible: Should be "socionext,uniphier-gpio".
-- reg: Specifies offset and length of the register set for the device.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be 2. The first cell is the pin number and the second
- cell is used to specify optional parameters.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be 2. The first cell defines the interrupt number.
- The second cell bits[3:0] is used to specify trigger type as follows:
- 1 = low-to-high edge triggered
- 2 = high-to-low edge triggered
- 4 = active high level-sensitive
- 8 = active low level-sensitive
- Valid combinations are 1, 2, 3, 4, 8.
-- ngpios: Specifies the number of GPIO lines.
-- gpio-ranges: Mapping to pin controller pins (as described in gpio.txt)
-- socionext,interrupt-ranges: Specifies an interrupt number mapping between
- this GPIO controller and its interrupt parent, in the form of arbitrary
- number of <child-interrupt-base parent-interrupt-base length> triplets.
-
-Optional properties:
-- gpio-ranges-group-names: Used for named gpio ranges (as described in gpio.txt)
-
-Example:
- gpio: gpio@55000000 {
- compatible = "socionext,uniphier-gpio";
- reg = <0x55000000 0x200>;
- interrupt-parent = <&aidet>;
- interrupt-controller;
- #interrupt-cells = <2>;
- gpio-controller;
- #gpio-cells = <2>;
- gpio-ranges = <&pinctrl 0 0 0>;
- gpio-ranges-group-names = "gpio_range";
- ngpios = <248>;
- socionext,interrupt-ranges = <0 48 16>, <16 154 5>, <21 217 3>;
- };
-
-Consumer Example:
-
- sdhci0_pwrseq {
- compatible = "mmc-pwrseq-emmc";
- reset-gpios = <&gpio UNIPHIER_GPIO_PORT(29, 4) GPIO_ACTIVE_LOW>;
- };
-
-Please note UNIPHIER_GPIO_PORT(29, 4) represents PORT294 in the SoC document.
-Unfortunately, only the one's place is octal in the port numbering. (That is,
-PORT 8, 9, 18, 19, 28, 29, ... are missing.) UNIPHIER_GPIO_PORT() is a helper

-* Rockchip RK3xxx I2C controller
-
-This driver interfaces with the native I2C controller present in Rockchip
-RK3xxx SoCs.
-
-Required properties :
-
- - reg : Offset and length of the register set for the device
- - compatible: should be one of the following:
- - "rockchip,rv1108-i2c": for rv1108
- - "rockchip,rk3066-i2c": for rk3066
- - "rockchip,rk3188-i2c": for rk3188
- - "rockchip,rk3228-i2c": for rk3228
- - "rockchip,rk3288-i2c": for rk3288
- - "rockchip,rk3328-i2c", "rockchip,rk3399-i2c": for rk3328
- - "rockchip,rk3399-i2c": for rk3399
- - interrupts : interrupt number
- - clocks: See ../clock/clock-bindings.txt
- - For older hardware (rk3066, rk3188, rk3228, rk3288):
- - There is one clock that's used both to derive the functional clock
- for the device and as the bus clock.
- - For newer hardware (rk3399): specified by name
- - "i2c": This is used to derive the functional clock.
- - "pclk": This is the bus clock.
-
-Required on RK3066, RK3188 :
-
- - rockchip,grf : the phandle of the syscon node for the general register
- file (GRF)
- - on those SoCs an alias with the correct I2C bus ID (bit offset in the GRF)
- is also required.
-
-Optional properties :
-
- - clock-frequency : SCL frequency to use (in Hz). If omitted, 100kHz is used.
- - i2c-scl-rising-time-ns : Number of nanoseconds the SCL signal takes to rise
- (t(r) in I2C specification). If not specified this is assumed to be
- the maximum the specification allows(1000 ns for Standard-mode,
- 300 ns for Fast-mode) which might cause slightly slower communication.
- - i2c-scl-falling-time-ns : Number of nanoseconds the SCL signal takes to fall
- (t(f) in the I2C specification). If not specified this is assumed to
- be the maximum the specification allows (300 ns) which might cause
- slightly slower communication.
- - i2c-sda-falling-time-ns : Number of nanoseconds the SDA signal takes to fall
- (t(f) in the I2C specification). If not specified we'll use the SCL
- value since they are the same in nearly all cases.
-
-Example:
-
-aliases {
- i2c0 = &i2c0;
-}
-
-i2c0: i2c@2002d000 {
- compatible = "rockchip,rk3188-i2c";
- reg = <0x2002d000 0x1000>;
- interrupts = <GIC_SPI 40 IRQ_TYPE_LEVEL_HIGH>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- rockchip,grf = <&grf>;
-
- clock-names = "i2c";
- clocks = <&cru PCLK_I2C0>;
-
- i2c-scl-rising-time-ns = <800>;
- i2c-scl-falling-time-ns = <100>;

-UniPhier AIDET
-
-UniPhier AIDET (ARM Interrupt Detector) is an add-on block for ARM GIC (Generic
-Interrupt Controller). GIC itself can handle only high level and rising edge
-interrupts. The AIDET provides logic inverter to support low level and falling
-edge interrupts.
-
-Required properties:
-- compatible: Should be one of the following:
- "socionext,uniphier-ld4-aidet" - for LD4 SoC
- "socionext,uniphier-pro4-aidet" - for Pro4 SoC
- "socionext,uniphier-sld8-aidet" - for sLD8 SoC
- "socionext,uniphier-pro5-aidet" - for Pro5 SoC
- "socionext,uniphier-pxs2-aidet" - for PXs2/LD6b SoC
- "socionext,uniphier-ld11-aidet" - for LD11 SoC
- "socionext,uniphier-ld20-aidet" - for LD20 SoC
- "socionext,uniphier-pxs3-aidet" - for PXs3 SoC
-- reg: Specifies offset and length of the register set for the device.
-- interrupt-controller: Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an interrupt
- source. The value should be 2. The first cell defines the interrupt number
- (corresponds to the SPI interrupt number of GIC). The second cell specifies
- the trigger type as defined in interrupts.txt in this directory.
-
-Example:
-
- aidet: aidet@5fc20000 {
- compatible = "socionext,uniphier-pro4-aidet";
- reg = <0x5fc20000 0x200>;
- interrupt-controller;

-Renesas R-Car Video Input driver (rcar_vin)
--------------------------------------------
-
-The rcar_vin device provides video input capabilities for the Renesas R-Car
-family of devices.
-
-Each VIN instance has a single parallel input that supports RGB and YUV video,
-with both external synchronization and BT.656 synchronization for the latter.
-Depending on the instance the VIN input is connected to external SoC pins, or
-on Gen3 and RZ/G2 platforms to a CSI-2 receiver.
-
- - compatible: Must be one or more of the following
- - "renesas,vin-r8a7743" for the R8A7743 device
- - "renesas,vin-r8a7744" for the R8A7744 device
- - "renesas,vin-r8a7745" for the R8A7745 device

-The per-board settings for Gen2 and RZ/G1 platforms:
-
-- port - sub-node describing a single endpoint connected to the VIN
- from external SoC pins as described in video-interfaces.txt[1].
- Only the first one will be considered as each vin interface has one
- input port.
-
- - Optional properties for endpoint nodes:
- - hsync-active: see [1] for description. Default is active high.
- - vsync-active: see [1] for description. Default is active high.
- If both HSYNC and VSYNC polarities are not specified, embedded
- synchronization is selected.
- - field-active-even: see [1] for description. Default is active high.
- - bus-width: see [1] for description. The selected bus width depends on

-The per-board settings for Gen3 and RZ/G2 platforms:
-
-Gen3 and RZ/G2 platforms can support both a single connected parallel input
-source from external SoC pins (port@0) and/or multiple parallel input sources
-from local SoC CSI-2 receivers (port@1) depending on SoC.
-
-- renesas,id - ID number of the VIN, VINx in the documentation.
-- ports
- - port@0 - sub-node describing a single endpoint connected to the VIN
- from external SoC pins as described in video-interfaces.txt[1].
- Describing more than one endpoint in port@0 is invalid. Only VIN
- instances that are connected to external pins should have port@0.
-
- Endpoint nodes of port@0 support the optional properties listed in
- the Gen2 per-board settings description.
-
- - port@1 - sub-nodes describing one or more endpoints connected to
- the VIN from local SoC CSI-2 receivers. The endpoint numbers must
- use the following schema.
-
- - endpoint@0 - sub-node describing the endpoint connected to CSI20
- - endpoint@1 - sub-node describing the endpoint connected to CSI21
- - endpoint@2 - sub-node describing the endpoint connected to CSI40
- - endpoint@3 - sub-node describing the endpoint connected to CSI41
-
- Endpoint nodes of port@1 do not support any optional endpoint property.

+
+description:
+ The R-Car Video Input (VIN) device provides video input capabilities for the
+ Renesas R-Car family of devices.
+
+ Each VIN instance has a single parallel input that supports RGB and YUV video,
+ with both external synchronization and BT.656 synchronization for the latter.
+ Depending on the instance the VIN input is connected to external SoC pins, or
+ on Gen3 and RZ/G2 platforms to a CSI-2 receiver.

-Generic CAN transceiver Device Tree binding
-------------------------------
-
-CAN transceiver typically limits the max speed in standard CAN and CAN FD
-modes. Typically these limitations are static and the transceivers themselves
-provide no way to detect this limitation at runtime. For this situation,
-the "can-transceiver" node can be used.
-
-Required Properties:
- max-bitrate: a positive non 0 value that determines the max
- speed that CAN/CAN-FD can run. Any other value
- will be ignored.
-
-Examples:
-
-Based on Texas Instrument's TCAN1042HGV CAN Transceiver
-
-m_can0 {
- ....
- can-transceiver {
- max-bitrate = <5000000>;
- };
- ...
-};

- - clock-output-names : specify the 480m output clock name.
-
-Optional properties:
- - clocks : phandle + phy specifier pair, for the input clock of phy.
- - clock-names : input clock name of phy, must be "phyclk".
- - assigned-clocks : phandle of usb 480m clock.
- - assigned-clock-parents : parent of usb 480m clock, select between
- usb-phy output 480m and xin24m.
- Refer to clk/clock-bindings.txt for generic clock
- consumer properties.
- - rockchip,usbgrf : phandle to the syscon managing the "usb general
- register files". When set driver will request its
- phandle as one companion-grf for some special SoCs
- (e.g RV1108).
- - extcon : phandle to the extcon device providing the cable state for
- the otg phy.
-
-Required nodes : a sub-node is required for each port the phy provides.
- The sub-node name is used to identify host or otg port,
- and shall be the following entries:
- * "otg-port" : the name of otg port.
- * "host-port" : the name of host port.
-
-Required properties (port (child) node):
- - #phy-cells : must be 0. See ./phy-bindings.txt for details.
- - interrupts : specify an interrupt for each entry in interrupt-names.
- - interrupt-names : a list which should be one of the following cases:
- Regular case:
- * "otg-id" : for the otg id interrupt.
- * "otg-bvalid" : for the otg vbus interrupt.
- * "linestate" : for the host/otg linestate interrupt.
- Some SoCs use one interrupt with the above muxed together, so for these
- * "otg-mux" : otg-port interrupt, which mux otg-id/otg-bvalid/linestate
- to one.
-
-Optional properties:
- - phy-supply : phandle to a regulator that provides power to VBUS.
- See ./phy-bindings.txt for details.
-
-Example:
-
-grf: syscon@ff770000 {
- compatible = "rockchip,rk3366-grf", "syscon", "simple-mfd";
- #address-cells = <1>;

-STMicroelectronics STPMIC1 Voltage regulators
-
-Regulator Nodes are optional depending on needs.
-
-Available Regulators in STPMIC1 device are:
- - buck1 for Buck BUCK1
- - buck2 for Buck BUCK2
- - buck3 for Buck BUCK3
- - buck4 for Buck BUCK4
- - ldo1 for LDO LDO1
- - ldo2 for LDO LDO2
- - ldo3 for LDO LDO3
- - ldo4 for LDO LDO4
- - ldo5 for LDO LDO5
- - ldo6 for LDO LDO6
- - vref_ddr for LDO Vref DDR
- - boost for Buck BOOST
- - pwr_sw1 for VBUS_OTG switch
- - pwr_sw2 for SW_OUT switch
-
-Switches are fixed voltage regulators with only enable/disable capability.
-
-Optional properties:
-- st,mask-reset: mask reset for this regulator: the regulator configuration
- is maintained during pmic reset.
-- regulator-over-current-protection:
- if set, all regulators are switched off in case of over-current detection
- on this regulator,
- if not set, the driver only sends an over-current event.
-- interrupts: index of current limit detection interrupt
-- <regulator>-supply: phandle to the parent supply/regulator node
- each regulator supply can be described except vref_ddr.
-- regulator-active-discharge: can be used on pwr_sw1 and pwr_sw2.
-
-Example:
-regulators {
- compatible = "st,stpmic1-regulators";
-
- ldo6-supply = <&v3v3>;
-
- vdd_core: buck1 {
- regulator-name = "vdd_core";

-
- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first, followed by the
- family-specific and/or generic versions.
-
- - reg: Base address and length of the I/O registers used by the UART.
- - interrupts: Must contain one or more interrupt-specifiers for the SCIx.
- If a single interrupt is expressed, then all events are
- multiplexed into this single interrupt.
-
- If multiple interrupts are provided by the hardware, the order
- in which the interrupts are listed must match order below. Note
- that some HW interrupt events may be muxed together resulting
- in duplicate entries.
- The interrupt order is as follows:
- 1. Error (ERI)
- 2. Receive buffer full (RXI)
- 3. Transmit buffer empty (TXI)
- 4. Break (BRI)
- 5. Data Ready (DRI)
- 6. Transmit End (TEI)
-
- - clocks: Must contain a phandle and clock-specifier pair for each entry
- in clock-names.
- - clock-names: Must contain "fck" for the SCIx UART functional clock.
- Apart from the divided functional clock, there may be other possible
- sources for the sampling clock, depending on SCIx variant.
- On (H)SCI(F) and some SCIFA, an additional clock may be specified:
- - "hsck" for the optional external clock input (on HSCIF),
- - "sck" for the optional external clock input (on other variants).
- On UARTs equipped with a Baud Rate Generator for External Clock (BRG)
- (some SCIF and HSCIF), additional clocks may be specified:
- - "brg_int" for the optional internal clock source for the frequency
- divider (typically the (AXI or SHwy) bus clock),
- - "scif_clk" for the optional external clock source for the frequency
- divider (SCIF_CLK).
-
-Note: Each enabled SCIx UART may have an optional "serialN" alias in the
-"aliases" node.
-
-Optional properties:
- - dmas: Must contain a list of two references to DMA specifiers, one for
- transmission, and one for reception.
- - dma-names: Must contain a list of two DMA names, "tx" and "rx".
- - {cts,dsr,dcd,rng,rts,dtr}-gpios: Specify GPIOs for modem lines, cfr. the
- generic serial DT bindings in serial.txt.
- - uart-has-rtscts: Indicates dedicated lines for RTS/CTS hardware flow
- control, cfr. the generic serial DT bindings in serial.txt.
-
-Example:
- aliases {
- serial0 = &scifa0;
- };
-
- scifa0: serial@e6c40000 {
- compatible = "renesas,scifa-r8a7790",
- "renesas,rcar-gen2-scifa", "renesas,scifa";

-Generic Serial DT Bindings
-
-This document lists a set of generic properties for describing UARTs in a
-device tree. Whether these properties apply to a particular device depends on
-the DT bindings for the actual device.
-
-Optional properties:
- - cts-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's CTS line.
- - dcd-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's DCD line.
- - dsr-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's DSR line.
- - dtr-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's DTR line.
- - rng-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's RNG line.
- - rts-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's RTS line.
-
- - uart-has-rtscts: The presence of this property indicates that the
- UART has dedicated lines for RTS/CTS hardware flow control, and that
- they are available for use (wired and enabled by pinmux configuration).
- This depends on both the UART hardware and the board wiring.
- Note that this property is mutually-exclusive with "cts-gpios" and
- "rts-gpios" above, unless support is provided to switch between modes
- dynamically.
-
-
-Examples:
-
- uart1: serial@48022000 {
- compatible = "ti,am3352-uart", "ti,omap3-uart";
- ti,hwmods = "uart2";
- clock-frequency = <48000000>;

-Qualcomm Quad Serial Peripheral Interface (QSPI)
-
-The QSPI controller allows SPI protocol communication in single, dual, or quad
-wire transmission modes for read/write access to slaves such as NOR flash.
-
-Required properties:
-- compatible: An SoC specific identifier followed by "qcom,qspi-v1", such as
- "qcom,sdm845-qspi", "qcom,qspi-v1"
-- reg: Should contain the base register location and length.
-- interrupts: Interrupt number used by the controller.
-- clocks: Should contain the core and AHB clock.
-- clock-names: Should be "core" for core clock and "iface" for AHB clock.
-
-SPI slave nodes must be children of the SPI master node and can contain
-properties described in Documentation/devicetree/bindings/spi/spi-bus.txt
-
-Example:
-
- qspi: spi@88df000 {
- compatible = "qcom,sdm845-qspi", "qcom,qspi-v1";
- reg = <0x88df000 0x600>;

- #size-cells = <0>;
- interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;
- clock-names = "iface", "core";
- clocks = <&gcc GCC_QSPI_CNOC_PERIPH_AHB_CLK>,
