1twl4030 GPIO controller bindings
2
3Required properties:
4- compatible:
5  - "ti,twl4030-gpio" for twl4030 GPIO controller
6- #gpio-cells : Should be two.
7  - first cell is the pin number
8  - second cell is used to specify optional parameters (unused)
9- gpio-controller : Marks the device node as a GPIO controller.
10- #interrupt-cells : Should be 2.
11- interrupt-controller: Mark the device node as an interrupt controller
12  The first cell is the GPIO number.
13  The second cell is not used.

17twl_gpio: gpio {
18    compatible = "ti,twl4030-gpio";
19    #gpio-cells = <2>;
20    gpio-controller;
21    #interrupt-cells = <2>;
22    interrupt-controller;
23};
