^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) BCM2835 PWM controller (Raspberry Pi controller)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) - compatible: should be "brcm,bcm2835-pwm"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) - reg: physical base address and length of the controller's registers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) - clocks: This clock defines the base clock frequency of the PWM hardware
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7)   system, the period and the duty_cycle of the PWM signal is a multiple of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8)   the base period.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) - #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)   the cells format.
