+Tegra SoC PWFM controller
+
+Required properties:
+- compatible: For Tegra20, must contain "nvidia,tegra20-pwm".  For Tegra30,
+  must contain "nvidia,tegra30-pwm".  Otherwise, must contain
+  "nvidia,<chip>-pwm", plus one of the above, where <chip> is tegra114,
+  tegra124, tegra132, or tegra210.
+- reg: physical base address and length of the controller's registers
+- #pwm-cells: should be 2. See pwm.txt in this directory for a description of
+  the cells format.
+- clocks: Must contain one entry, for the module clock.
+  See ../clocks/clock-bindings.txt for details.
+- resets: Must contain an entry for each entry in reset-names.
+  See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+  - pwm
+
+Example:
+
+       pwm: pwm@7000a000 {
+               compatible = "nvidia,tegra20-pwm";
+               reg = <0x7000a000 0x100>;
+               #pwm-cells = <2>;
+               clocks = <&tegra_car 17>;
+               resets = <&tegra_car 17>;
+               reset-names = "pwm";
+       };
