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>;
+};
