+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),
+ "ftm_cnt_clk_en" (external and fixed counter clock enable/disable).
+- clocks: Must contain a phandle and clock specifier for each entry in
+ clock-names, please 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.
