   1 Tegra SoC PWFM controller
   2
   3 Required properties:
   4 - compatible: should be one of:
   5   - "nvidia,tegra20-pwm"
   6   - "nvidia,tegra30-pwm"
   7 - reg: physical base address and length of the controller's registers
   8 - #pwm-cells: On Tegra the number of cells used to specify a PWM is 2. The
   9   first cell specifies the per-chip index of the PWM to use and the second
  10   cell is the period in nanoseconds.

  12 Example:
  13
  14         pwm: pwm@7000a000 {
  15                 compatible = "nvidia,tegra20-pwm";
  16                 reg = <0x7000a000 0x100>;
  17                 #pwm-cells = <2>;
  18         };
