|
Required properties:
|
|
- compatible = "gpio-keys-polled";
|
|
- poll-interval: Poll interval time in milliseconds
|
|
|
|
Optional properties:
|
|
- autorepeat: Boolean, Enable auto repeat feature of Linux input

subsystem.
|
|
|
|
Each button (key) is represented as a sub-node of "gpio-keys-polled":
|
|
Subnode properties:
|
|
|
|
- gpios: OF device-tree gpio specification.
|
|
- label: Descriptive name of the key.
|
|
- linux,code: Keycode to emit.
|
|
|
|
Optional subnode-properties:
|
|
- linux,input-type: Specify event type this button/key generates.
|
|
If not specified defaults to <1> == EV_KEY.
|
|
- debounce-interval: Debouncing interval time in milliseconds.

gpio_keys_polled {
|
|
compatible = "gpio-keys-polled";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
