|
|
- "renesas,gpio-r8a77995": for R8A77995 (R-Car D3) compatible GPIO controller.
|
|
- "renesas,rcar-gen1-gpio": for a generic R-Car Gen1 GPIO controller.
|
|
- "renesas,rcar-gen2-gpio": for a generic R-Car Gen2 or RZ/G1 GPIO controller.
|
|
- "renesas,rcar-gen3-gpio": for a generic R-Car Gen3 or RZ/G2 GPIO controller.

|
|
|
|
When compatible with the generic version nodes must list the
|
|
SoC-specific version corresponding to the platform first followed by
|
|
the generic version.
|
|
|
|
- reg: Base address and length of each memory resource used by the GPIO
|
|
controller hardware module.
|
|
|
|
- interrupts: Interrupt specifier for the controllers interrupt.
|
|
|
|
- gpio-controller: Marks the device node as a gpio controller.
|
|
- #gpio-cells: Should be 2. The first cell is the GPIO number and the second
|
|
cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
|
|
GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
|
|
- gpio-ranges: See gpio.txt.
|
|
|
|
Optional properties:
|
|
|
|
- clocks: Must contain a reference to the functional clock. The property is
|
|
mandatory if the hardware implements a controllable functional clock for
|
|
the GPIO instance.
|
|
|
|
- gpio-reserved-ranges: See gpio.txt.
|
|
|
|
Please refer to gpio.txt in this directory for the common GPIO bindings used by
|
|
client devices.
|
|
|
|
The GPIO controller also acts as an interrupt controller. It uses the default
|
|
two cells specifier as described in Documentation/devicetree/bindings/
|
|
interrupt-controller/interrupts.txt.
