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" or
10			  "xlnx,zynqmp-gpio-1.0" or "xlnx,versal-gpio-1.0
11			  or "xlnx,pmc-gpio-1.0
12- clocks		: Clock specifier (see clock bindings for details)
13- gpio-controller	: Marks the device node as a GPIO controller.
14- interrupts		: Interrupt specifier (see interrupt bindings for
15			  details)
16- interrupt-controller	: Marks the device node as an interrupt controller.
17- #interrupt-cells 	: Should be 2.  The first cell is the GPIO number.
18			  The second cell bits[3:0] is used to specify trigger type and level flags:
19			      1 = low-to-high edge triggered.
20			      2 = high-to-low edge triggered.
21			      4 = active high level-sensitive.
22			      8 = active low level-sensitive.
23- reg			: Address and length of the register set for the device

25Example:
26	gpio@e000a000 {
27		#gpio-cells = <2>;
28		compatible = "xlnx,zynq-gpio-1.0";
29		clocks = <&clkc 42>;
30		gpio-controller;
31		interrupt-parent = <&intc>;
32		interrupts = <0 20 4>;
33		interrupt-controller;
34		#interrupt-cells = <2>;
35		reg = <0xe000a000 0x1000>;
36	};
