Binding for Qualcomm Atheros AR7xxx/AR9xxx GPIO controller



Required properties:

- compatible: has to be "qca,<soctype>-gpio" and one of the following

  fallbacks:

  - "qca,ar7100-gpio"

  - "qca,ar9340-gpio"

- reg: Base address and size of the controllers memory area

- gpio-controller : Marks the device node as a GPIO controller.

- #gpio-cells : Should be two. The first cell is the pin number and the

  second cell is used to specify optional parameters.

- ngpios: Should be set to the number of GPIOs available on the SoC.



Optional properties:

- interrupts: Interrupt specifier for the controllers interrupt.

- interrupt-controller : Identifies the node as an interrupt controller

- #interrupt-cells : Specifies the number of cells needed to encode interrupt

		     source, should be 2



Please refer to interrupts.txt in this directory for details of the common

Interrupt Controllers bindings used by client devices.



Example:



	gpio@18040000 {

		compatible = "qca,ar9132-gpio", "qca,ar7100-gpio";

		reg = <0x18040000 0x30>;

		interrupts = <2>;



		ngpios = <22>;



		gpio-controller;

		#gpio-cells = <2>;



		interrupt-controller;

		#interrupt-cells = <2>;

	};
