0001 * GPIO beeper device tree bindings
0002
0003 Register a beeper connected to GPIO pin.
0004
0005 Required properties:
0006 - compatible:   Should be "gpio-beeper".
0007 - gpios:        From common gpio binding; gpio connection to beeper enable pin.
0008
0009 Example:
0010         beeper: beeper {
0011                 compatible = "gpio-beeper";
0012                 gpios = <&gpio3 23 GPIO_ACTIVE_HIGH>;
0013         };
