* 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>;
};
