Device-Tree bindings for input/gpio_keys_polled.c keyboard driver
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.
If not specified defaults to 5.
- gpio-key,wakeup: Boolean, button can wake-up the system.
Example nodes:
gpio_keys_polled {
compatible = "gpio-keys-polled";
#address-cells = <1>;
#size-cells = <0>;
poll-interval = <100>;
autorepeat;
button@21 {
label = "GPIO Key UP";
linux,code = <103>;
gpios = <&gpio1 0 1>;
};

Rotary encoder DT bindings
Required properties:
- gpios: a spec for two GPIOs to be used
Optional properties:
- linux,axis: the input subsystem axis to map to this rotary encoder.
Defaults to 0 (ABS_X / REL_X)
- rotary-encoder,steps: Number of steps in a full turnaround of the
encoder. Only relevant for absolute axis. Defaults to 24 which is a
typical value for such devices.
- rotary-encoder,relative-axis: register a relative axis rather than an
absolute one. Relative axis will only generate +1/-1 events on the input
device, hence no steps need to be passed.
- rotary-encoder,rollover: Automatic rollove when the rotary value becomes
greater than the specified steps or smaller than 0. For absolute axis only.
- rotary-encoder,half-period: Makes the driver work on half-period mode.
See Documentation/input/rotary-encoder.txt for more information.
Example:
rotary@0 {
compatible = "rotary-encoder";
gpios = <&gpio 19 1>, <&gpio 20 0>; /* GPIO19 is inverted */
linux,axis = <0>; /* REL_X */
rotary-encoder,relative-axis;
};
rotary@1 {
compatible = "rotary-encoder";
gpios = <&gpio 21 0>, <&gpio 22 0>;
linux,axis = <1>; /* ABS_Y */
rotary-encoder,steps = <24>;
rotary-encoder,rollover;
};
