+Freescale i.MX PWM controller
+
+Required properties:
+- compatible : should be "fsl,<soc>-pwm" and one of the following
+   compatible strings:
+  - "fsl,imx1-pwm" for PWM compatible with the one integrated on i.MX1
+  - "fsl,imx27-pwm" for PWM compatible with the one integrated on i.MX27
+- reg: physical base address and length of the controller's registers
+- #pwm-cells: 2 for i.MX1 and 3 for i.MX27 and newer SoCs. See pwm.txt
+  in this directory for a description of the cells format.
+- clocks : Clock specifiers for both ipg and per clocks.
+- clock-names : Clock names should include both "ipg" and "per"
+See the clock consumer binding,
+	Documentation/devicetree/bindings/clock/clock-bindings.txt
+- interrupts: The interrupt for the pwm controller
+
+Example:
+
+pwm1: pwm@53fb4000 {
+	#pwm-cells = <3>;
+	compatible = "fsl,imx53-pwm", "fsl,imx27-pwm";
+	reg = <0x53fb4000 0x4000>;
+	clocks = <&clks IMX5_CLK_PWM1_IPG_GATE>,
+		 <&clks IMX5_CLK_PWM1_HF_GATE>;
+	clock-names = "ipg", "per";
+	interrupts = <61>;
+};
