Description
***********



.. code-block:: none

   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>;
   };
