The RFC patch only added "See ../clock/clock-bindings.txt for details of
the property values."
This adds the Document for Freescale FTM PWM driver under
Documentation/devicetree/bindings/pwm/.

+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,
+ See ../clock/clock-bindings.txt for details of the property values.
+- 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";
+};
