1 | twl4030 GPIO controller bindings | ||
2 | |||
3 | Required 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. | ||
14 | |||

16 | |||
17 | twl_gpio: gpio { | ||
18 | compatible = "ti,twl4030-gpio"; | ||
19 | #gpio-cells = <2>; | ||
