Subject: [RFC][PATCHv5 4/4] Documentation: Add device tree bindings for Freescale FTM PWM.

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@...38000 {
+		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";
+};
