+Freescale MXS PWM controller
+
+Required properties:
+- compatible: should be "fsl,mxs-pwm"
+- reg: physical base address and length of the controller's registers
+- #pwm-cells: should be 2. The first cell specifies the per-chip index
+ of the PWM to use and the second cell is the duty cycle in nanoseconds.
+- fsl,pwm-number: the number of PWM devices
+
+Example:
+
+pwm: pwm@80064000 {
+ compatible = "fsl,imx28-pwm", "fsl,mxs-pwm";
+ reg = <0x80064000 2000>;
+ #pwm-cells = <2>;
+ fsl,pwm-number = <8>;
+};
