* 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 | |
Example: | |
beeper_amp: amplifier { | |
compatible = "fixed-regulator"; | |
gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>; | |
}; | |
beeper { | |
compatible = "pwm-beeper"; | |
pwms = <&pwm0>; | |
amp-supply = <&beeper_amp>; | |
}; |
