   1 Tegra SoC PWFM controller
   2
   3 Required properties:
   4 - compatible: Must be:
   5   - "nvidia,tegra20-pwm": for Tegra20
   6   - "nvidia,tegra30-pwm", "nvidia,tegra20-pwm": for Tegra30
   7   - "nvidia,tegra114-pwm", "nvidia,tegra20-pwm": for Tegra114
   8   - "nvidia,tegra124-pwm", "nvidia,tegra20-pwm": for Tegra124
   9   - "nvidia,tegra132-pwm", "nvidia,tegra20-pwm": for Tegra132
  10   - "nvidia,tegra210-pwm", "nvidia,tegra20-pwm": for Tegra210
  11   - "nvidia,tegra186-pwm": for Tegra186
  12 - reg: physical base address and length of the controller's registers
  13 - #pwm-cells: should be 2. See pwm.txt in this directory for a description of
  14   the cells format.
  15 - clocks: Must contain one entry, for the module clock.
  16   See ../clocks/clock-bindings.txt for details.
  17 - resets: Must contain an entry for each entry in reset-names.
  18   See ../reset/reset.txt for details.
  19 - reset-names: Must include the following entries:
  20   - pwm

  22 Example:
  23
  24         pwm: pwm@7000a000 {
  25                 compatible = "nvidia,tegra20-pwm";
  26                 reg = <0x7000a000 0x100>;
  27                 #pwm-cells = <2>;
  28                 clocks = <&tegra_car 17>;
  29                 resets = <&tegra_car 17>;
  30                 reset-names = "pwm";
  31         };
