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