    Subject[PATCH v3 02/14] Documentation: dt/bindings: Document pinctrl-gpio
    Date
    This commit adds documentation for the devicetree bidings of the
    pinctrl-gpio driver, which handles GPIOs of the Ingenic SoCs
    currently supported by the Linux kernel.

    +Ingenic jz47xx GPIO controller
    +
    +Required properties:
    + - compatible:
    + - "ingenic,jz4740-gpio" for the JZ4740 SoC
    + - "ingenic,jz4780-gpio" for the JZ4780 SoC
    +
    + - reg: Base address and length of each memory resource used by the GPIO
    + controller hardware module.
    +
    + - 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: Range of pins managed by the GPIO controller.
    +
    +Optional properties:
    + - base: The GPIO number to use as the base for this driver.
    + - interrupt-controller: Marks the device node as an interrupt controller.
    + - interrupts: Interrupt specifier for the controllers interrupt.
    + Required if 'interrupt-controller' is specified.
    +
    +Please refer to gpio.txt in this directory for details of gpio-ranges property
    +and 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.
    +
    +Example:
    +
    +gpa: gpio-controller@10010000 {
    + compatible = "ingenic,jz4740-gpio";
    + reg = <0x10010000 0x100>;
    +
    + gpio-controller;
    + gpio-ranges = <&pinctrl 0 0 32>;
    + #gpio-cells = <2>;
    +
    + interrupt-controller;
    + #interrupt-cells = <2>;
    +
    + interrupt-parent = <&intc>;
    + interrupts = <28>;
    +};
