   1 Freescale MXS PWM controller
   2
   3 Required properties:
   4 - compatible: should be "fsl,imx23-pwm"
   5 - reg: physical base address and length of the controller's registers
   6 - #pwm-cells: should be 2.  The first cell specifies the per-chip index
   7   of the PWM to use and the second cell is the duty cycle in nanoseconds.
   8 - fsl,pwm-number: the number of PWM devices
   9
  10 Example:
  11
  12 pwm: pwm@80064000 {
  13         compatible = "fsl,imx28-pwm", "fsl,imx23-pwm";
  14         reg = <0x80064000 2000>;
  15         #pwm-cells = <2>;
  16         fsl,pwm-number = <8>;
  17 };
