Aspeed GPIO controller Device Tree Bindings

-------------------------------------------



Required properties:

- compatible		: Either "aspeed,ast2400-gpio", "aspeed,ast2500-gpio",

					or "aspeed,ast2600-gpio".



- #gpio-cells 		: Should be two

			  - First cell is the GPIO line number

			  - Second cell is used to specify optional

			    parameters (unused)



- reg			: Address and length of the register set for the device

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

- interrupts		: Interrupt specifier (see interrupt bindings for

			  details)

- interrupt-controller	: Mark the GPIO controller as an interrupt-controller



Optional properties:



- clocks		: A phandle to the clock to use for debounce timings

- ngpios		: Number of GPIOs controlled by this controller. Should	be set

				  when there are multiple GPIO controllers on a SoC (ast2600).



The gpio and interrupt properties are further described in their respective

bindings documentation:



- Documentation/devicetree/bindings/gpio/gpio.txt

- Documentation/devicetree/bindings/interrupt-controller/interrupts.txt



  Example:

	gpio@1e780000 {

		#gpio-cells = <2>;

		compatible = "aspeed,ast2400-gpio";

		gpio-controller;

		interrupts = <20>;

		reg = <0x1e780000 0x1000>;

		interrupt-controller;

	};
