| Zephyr Input GPIO KEYS parent node |
| |
| This defines a group of buttons that can generate input events. Each button |
| is defined in a child node of the gpio-keys node and defines a specific key |
| code. |
| |
| For example: |
| |
| #include <zephyr/dt-bindings/input/input-event-codes.h> |
| |
| / { |
| buttons { |
| compatible = "gpio-keys"; |
| button_0 { |
| gpios = <&gpio0 13 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>; |
| zephyr,code = <INPUT_KEY_0>; |
| }; |
| }; |
| }; |
| |
| |
| compatible: "gpio-keys" |
| |
| include: base.yaml |
| |
| properties: |
| debounce-interval-ms: |
| type: int |
| default: 30 |
| description: | |
| Debouncing interval time in milliseconds. |
| If not specified defaults to 30. |
| |
| polling-mode: |
| type: boolean |
| description: | |
| Do not use interrupts for the key GPIOs, poll the pin periodically at the |
| specified debounce-interval-ms instead. |
| |
| no-disconnect: |
| type: boolean |
| description: | |
| Do not try to disconnect the pin on suspend. Can be used if the GPIO |
| controller does not support the GPIO_DISCONNECTED flag. |
