   1 Rockchip PWM controller
   2
   3 Required properties:
   4 - compatible: should be "rockchip,<name>-pwm"
   5 - reg: physical base address and length of the controller's registers
   6 - #pwm-cells: should be 2.  The first cell specifies the per-chip index
   7   of the PWM to use and the second cell is the period in nanoseconds.
   8 - pinctrl-names: must contain a "default" entry.
   9 - pinctrl-0: the pincontrol settings to configurethe.
  10 - clocks: phandle to the PWM source clock
  11 - clock-names: list of clock names sorted in the same order as the clocks.
  12 - status: for device state control (enabled/disabled).

  25         #pwm-cells = <2>;
  26         pinctrl-names = "default";
  27         pinctrl-0 = <&pwm0_pin>;

  29         clock-names = "pclk_pwm";
  30         status = "disabled";
