    +Freescale FTM PWM controller
    +
    +Required properties:
    +- compatible: Should be "fsl,vf610-ftm-pwm"
    +- reg: Physical base address and length of the controller's registers
    +- #pwm-cells: Should be 3. See pwm.txt in this directory for a description of
    + the cells format.
    +- clock-names : Includes the following module clock source entries:
    + "ftm0" (system clock),
    + "ftm0_fix_sel" (fixed frequency clock),
    + "ftm0_ext_sel" (external clock)
    +- clocks : Must contain a clock specifier for each entry in clock-names.
    +- fsl,pwm-counter-clk: The FTM PWM counter clock source, should be one of the
    + entries in clock-names.
    +- pinctrl-names: must contain a "default" entry.
    +- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
    + See ../pinctrl/pinctrl-bindings.txt for details of the property values.
    +
    +
    +Example:
    +
    +pwm0: pwm@40038000 {
    + compatible = "fsl,vf610-ftm-pwm";
    + reg = <0x40038000 0x1000>;
    + #pwm-cells = <3>;
    + clock-names = "ftm0", "ftm0_fix_sel", "ftm0_ext_sel";
    + clocks = <&clks VF610_CLK_FTM0>,
    + <&clks VF610_CLK_FTM0_FIX_SEL>,
    + <&clks VF610_CLK_FTM0_EXT_SEL>;
    + pinctrl-names = "default";
    + pinctrl-0 = <&pinctrl_pwm0_1>;
    + fsl,pwm-counter-clk = "ftm0_ext_sel";
    +};
