-There is no reason to stick to a particular translation mapping, but the
-"ranges" property should provide a "reasonable" default that is known to work.
-The software should initialize the bus controller according to it.
-
-Example:
-
- system-bus {
- compatible = "socionext,uniphier-system-bus";
- reg = <0x58c00000 0x400>;
- #address-cells = <2>;
- #size-cells = <1>;
- ranges = <1 0x00000000 0x42000000 0x02000000
- 5 0x00000000 0x46000000 0x01000000>;
-
- ethernet@1,01f00000 {
- compatible = "smsc,lan9115";
- reg = <1 0x01f00000 0x1000>;
- interrupts = <0 48 4>
- phy-mode = "mii";
- };
-
- uart@5,00200000 {
- compatible = "ns16550a";
- reg = <5 0x00200000 0x20>;
- interrupts = <0 49 4>
- clock-frequency = <12288000>;
- };
- };
-
-In this example,
- - the Ethernet device is connected at the offset 0x01f00000 of CS1 and
- mapped to 0x43f00000 of the parent bus.
- - the UART device is connected at the offset 0x00200000 of CS5 and
- mapped to 0x46200000 of the parent bus.

-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>;

- <&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
-macro to calculate 29 * 8 + 4.

-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;
- #interrupt-cells = <2>;

+
+description: |
+ 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.

-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>;
- };
- ...
-};

-Bosch MCAN controller Device Tree Bindings
--------------------------------------------------

-Required properties:
-- compatible : Should be "bosch,m_can" for M_CAN controllers
-- reg : physical base address and size of the M_CAN
- registers map and Message RAM
-- reg-names : Should be "m_can" and "message_ram"
-- interrupts : Should be the interrupt number of M_CAN interrupt
- line 0 and line 1, could be same if sharing
- the same interrupt.
-- interrupt-names : Should contain "int0" and "int1"
-- clocks : Clocks used by controller, should be host clock
- and CAN clock.
-- clock-names : Should contain "hclk" and "cclk"
-- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
-- pinctrl-names : Names corresponding to the numbered pinctrl states
-- bosch,mram-cfg : Message RAM configuration data.
- Multiple M_CAN instances can share the same Message
- RAM and each element(e.g Rx FIFO or Tx Buffer and etc)
- number in Message RAM is also configurable,
- so this property is telling driver how the shared or
- private Message RAM are used by this M_CAN controller.

-- can-transceiver : Can-transceiver subnode describing maximum speed
- that can be used for CAN/CAN-FD modes. See
