1VIA/Wondermedia VT8500/WM8xxx series SoC PWM controller2 3Required properties:4- compatible: should be "via,vt8500-pwm"5- reg: physical base address and length of the controller's registers6- #pwm-cells: should be 3. See pwm.yaml in this directory for a description of7 the cells format. The only third cell flag supported by this binding is8 PWM_POLARITY_INVERTED.9- clocks: phandle to the PWM source clock10 11Example:12 13pwm1: pwm@d8220000 {14 #pwm-cells = <3>;15 compatible = "via,vt8500-pwm";16 reg = <0xd8220000 0x1000>;17 clocks = <&clkpwm>;18};19
