| 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 zephyr,gpio-keys node and define a specific |
| key code. |
| |
| For example: |
| |
| #include <dt-bindings/input/input-event-codes.h> |
| |
| / { |
| buttons { |
| compatible = "zephyr,gpio-keys"; |
| button_0 { |
| gpios = <&gpio0 13 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>; |
| zephyr,code = <INPUT_KEY_0>; |
| }; |
| }; |
| }; |
| |
| compatible: "zephyr,gpio-keys" |
| |
| include: [gpio-keys.yaml] |
| |
| child-binding: |
| properties: |
| zephyr,code: |
| required: true |
