+Freescale FlexTimer Module (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 : Should include the following module clock source entries:
+ "ftm_sys" (module clock, also can be used as counter clock),
+ "ftm_ext" (external counter clock),
+ "ftm_fix" (fixed counter clock),
+- clocks : Must contain a clock specifier for each entry in clock-names,
+ See clock/clock-bindings.txt for details of the property values.
+- 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.
+- big-endian: If this property is absent, the little endian mode will be in
+ use as default, or the big endian mode will be in use for all the device
+ registers.
+
+
+Example:
+
+pwm0: pwm@40038000 {
+ compatible = "fsl,vf610-ftm-pwm";
+ reg = <0x40038000 0x1000>;
+ #pwm-cells = <3>;
+ clock-names = "ftm_sys", "ftm_ext", "ftm_fix";
+ clocks = <&clks VF610_CLK_FTM0>,
+ <&clks VF610_CLK_FTM0_EXT_SEL>,
+ <&clks VF610_CLK_FTM0_FIX_SEL>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_pwm0_1>;
+ big-endian;
+};
