1Xilinx Zynq GPIO controller Device Tree Bindings
2-------------------------------------------
3
4Required properties:
5- #gpio-cells 		: Should be two
6			  - First cell is the GPIO line number
7			  - Second cell is used to specify optional
8			    parameters (unused)
9- compatible		: Should be "xlnx,zynq-gpio-1.0"
10- clocks		: Clock specifier (see clock bindings for details)
11- gpio-controller	: Marks the device node as a GPIO controller.
12- interrupts		: Interrupt specifier (see interrupt bindings for
13			  details)
14- interrupt-parent	: Must be core interrupt controller
15- reg			: Address and length of the register set for the device
16
17Example:
18	gpio@e000a000 {
19		#gpio-cells = <2>;
20		compatible = "xlnx,zynq-gpio-1.0";
21		clocks = <&clkc 42>;
22		gpio-controller;
23		interrupt-parent = <&intc>;
24		interrupts = <0 20 4>;
25		reg = <0xe000a000 0x1000>;
26	};
