1Device-Tree bindings for input/gpio_keys.c keyboard driver
2
3Required properties:
4 - compatible = "gpio-keys";
5
6Optional properties:
7 - autorepeat: Boolean, Enable auto repeat feature of Linux input
8 subsystem.
9
10Each button (key) is represented as a sub-node of "gpio-keys":
11Subnode properties:
12
13 - gpios: OF devcie-tree gpio specificatin.
14 - label: Descriptive name of the key.
15 - linux,code: Keycode to emit.
16
17Optional subnode-properties:
18 - linux,input-type: Specify event type this button/key generates.
19 If not specified defaults to <1> == EV_KEY.
20 - debounce-interval: Debouncing interval time in milliseconds.
21 If not specified defaults to 5.
22 - gpio-key,wakeup: Boolean, button can wake-up the system.
23
24Example nodes:
25
26 gpio_keys {
27 compatible = "gpio-keys";
28 #address-cells = <1>;
29 #size-cells = <0>;
30 autorepeat;
31 button@21 {
32 label = "GPIO Key UP";
33 linux,code = <103>;
34 gpios = <&gpio1 0 1>;
