   3 Required properties:
   4   - compatible: Should be "img,pistachio-pwm"
   5   - reg: Should contain physical base address and length of pwm registers.
   6   - clocks: Must contain an entry for each entry in clock-names.
   7         See ../clock/clock-bindings.txt for details.
   8   - clock-names: Must include the following entries.
   9     - pwm: PWM operating clock.
  10     - sys: PWM system interface clock.
  11   - #pwm-cells: Should be 2. See pwm.txt in this directory for the
  12         description of the cells format.
  13   - img,cr-periph: Must contain a phandle to the peripheral control
  14         syscon node which contains PWM control registers.
