| * 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>; | |
| }; |
