   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.
