   1 Freescale i.MX PWM controller
   2
   3 Required properties:
   4 - compatible : should be "fsl,<soc>-pwm" and one of the following
   5    compatible strings:
   6   - "fsl,imx1-pwm" for PWM compatible with the one integrated on i.MX1
   7   - "fsl,imx27-pwm" for PWM compatible with the one integrated on i.MX27
   8 - reg: physical base address and length of the controller's registers
   9 - #pwm-cells: should be 2. See pwm.txt in this directory for a description of
  10   the cells format.
  11 - clocks : Clock specifiers for both ipg and per clocks.
  12 - clock-names : Clock names should include both "ipg" and "per"
  13 See the clock consumer binding,
  14         Documentation/devicetree/bindings/clock/clock-bindings.txt
  15 - interrupts: The interrupt for the pwm controller
  16
  17 Example:
  18
  19 pwm1: pwm@53fb4000 {
  20         #pwm-cells = <2>;
  21         compatible = "fsl,imx53-pwm", "fsl,imx27-pwm";
  22         reg = <0x53fb4000 0x4000>;
  23         clocks = <&clks IMX5_CLK_PWM1_IPG_GATE>,
  24                  <&clks IMX5_CLK_PWM1_HF_GATE>;
  25         clock-names = "ipg", "per";
  26         interrupts = <61>;
  27 };
