-VIA/Wondermedia VT8500/WM8xxx series SoC PWM controller
-
-Required properties:
-- compatible: should be "via,vt8500-pwm"
-- reg: physical base address and length of the controller's registers
-- #pwm-cells: should be 3. See pwm.yaml in this directory for a description of
-  the cells format. The only third cell flag supported by this binding is
-  PWM_POLARITY_INVERTED.
-- clocks: phandle to the PWM source clock
-
-Example:
-
-pwm1: pwm@d8220000 {
-	#pwm-cells = <3>;
-	compatible = "via,vt8500-pwm";
-	reg = <0xd8220000 0x1000>;
-	clocks = <&clkpwm>;
-};
