^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Registers a PWM device as beeper.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) - compatible: should be "pwm-beeper"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) - pwms: phandle to the physical PWM device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - amp-supply: phandle to a regulator that acts as an amplifier for the beeper
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) - beeper-hz:  bell frequency in Hz
