   6 Required properties:
   7  - compatible: value should be one of the following:
   8    "atmel,hlcdc-pwm"
   9  - pinctr-names: the pin control state names. Should contain "default".
  10  - pinctrl-0: should contain the pinctrl states described by pinctrl
  11    default.
  12  - #pwm-cells: should be set to 3. This PWM chip use the default 3 cells
  13    bindings defined in pwm.txt in this directory.
