1Bindings for the Western Digital's MyBook Live memory-mapped GPIO controllers.
2
3The Western Digital MyBook Live has two memory-mapped GPIO controllers.
4Both GPIO controller only have a single 8-bit data register, where GPIO
5state can be read and/or written.
6
7Required properties:
8	- compatible: should be "wd,mbl-gpio"
9	- reg-names: must contain
10		"dat" - data register
11	- reg: address + size pairs describing the GPIO register sets;
12		order must correspond with the order of entries in reg-names
13	- #gpio-cells: must be set to 2. The first cell is the pin number and
14			the second cell is used to specify the gpio polarity:
15			0 = active high
16			1 = active low
17	- gpio-controller: Marks the device node as a gpio controller.
18
19Optional properties:
20	- no-output: GPIOs are read-only.

22Examples:
23	gpio0: gpio0@e0000000 {
24		compatible = "wd,mbl-gpio";
25		reg-names = "dat";
26		reg = <0xe0000000 0x1>;
27		#gpio-cells = <2>;
28		gpio-controller;
29	};
30
31	gpio1: gpio1@e0100000 {
32		compatible = "wd,mbl-gpio";
33		reg-names = "dat";
34		reg = <0xe0100000 0x1>;
35		#gpio-cells = <2>;
36		gpio-controller;
37		no-output;
38	};
