zephyr,lvgl-keypad-input

Vendor: Zephyr-specific binding

Description

LVGL keypad indev pseudo-device

Listens for input events and routes the
lv_indev_data_t to the underlying keypad lv_indev_t managed by LVGL.

The property input-codes can be used to setup a mapping of input codes
to the lvgl keys. There are lvgl keys that have a special function:
https://docs.lvgl.io/master/overview/indev.html#keys.

The pseudo device can be associated to a specific device to listen only
for events from that device. Example configuration:

#include <zephyr/dt-bindings/lvgl/lvgl.h>

keypad {
        compatible = "zephyr,lvgl-keypad-input";
        input = <&buttons>;
        input-codes = <INPUT_KEY_1 INPUT_KEY_2>;
        lvgl-codes = <LV_KEY_NEXT LV_KEY_PREV>;
};
