1 * PWM beeper device tree bindings
3 Registers a PWM device as beeper.
6 - compatible: should be "pwm-beeper"
7 - pwms: phandle to the physical PWM device
10 - amp-supply: phandle to a regulator that acts as an amplifier for the beeper

15 compatible = "fixed-regulator";
16 gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;
20 compatible = "pwm-beeper";
22 amp-supply = <&beeper_amp>;
