+* GPIO beeper device tree bindings
+Register a beeper connected to GPIO pin.
+Required properties:
+- compatible: Should be "gpio-beeper".
+- gpios: From common gpio binding; gpio connection to beeper enable pin.
+ beeper: beeper {
+ compatible = "gpio-beeper";
+ gpios = <&gpio3 23 GPIO_ACTIVE_HIGH>;
