  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]
