-Device-Tree bindings for input/keyboard/gpio_keys.c keyboard driver
-
-Required properties:
- - compatible = "gpio-keys";
-
-Optional properties:
- - autorepeat: Boolean, Enable auto repeat feature of Linux input
- subsystem.
- - label: String, name of the input device.
-
-Each button (key) is represented as a sub-node of "gpio-keys":
-Subnode properties:
-
- - gpios: OF device-tree gpio specification.
- - interrupts: the interrupt line for that input.
- - label: Descriptive name of the key.
- - linux,code: Keycode to emit.
-
-Note that either "interrupts" or "gpios" properties can be omitted, but not
-both at the same time. Specifying both properties is allowed.
-
-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.
- - wakeup-source: Boolean, button can wake-up the system.
- (Legacy property supported: "gpio-key,wakeup")
- - wakeup-event-action: Specifies whether the key should wake the
- system when asserted, when deasserted, or both. This property is
- only valid for keys that wake up the system (e.g., when the
- "wakeup-source" property is also provided).
- Supported values are defined in linux-event-codes.h:
- EV_ACT_ASSERTED - asserted
- EV_ACT_DEASSERTED - deasserted
- EV_ACT_ANY - both asserted and deasserted
- - linux,can-disable: Boolean, indicates that button is connected
- to dedicated (not shared) interrupt which can be disabled to
- suppress events from the button.
-
-Example nodes:
-
- gpio-keys {
- compatible = "gpio-keys";
- autorepeat;
-
- up {
- label = "GPIO Key UP";
- linux,code = <103>;
- gpios = <&gpio1 0 1>;
- };
-
- down {
- label = "GPIO Key DOWN";
- linux,code = <108>;
- interrupts = <1 IRQ_TYPE_LEVEL_HIGH 7>;
- };
- ...
