- * PWM beeper device tree bindings
- Registers a PWM device as beeper.
- Required properties:
- - compatible: should be "pwm-beeper"
- - pwms: phandle to the physical PWM device
- Optional properties:
- - amp-supply: phandle to a regulator that acts as an amplifier for the beeper
- - beeper-hz: bell frequency in Hz
- Example:
- beeper_amp: amplifier {
- compatible = "fixed-regulator";
- gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;
- };
- beeper {
- compatible = "pwm-beeper";
- pwms = <&pwm0>;
- amp-supply = <&beeper_amp>;
- };
