1VIA/Wondermedia VT8500/WM8xxx series SoC PWM controller 2 3Required properties: 4- compatible: should be "via,vt8500-pwm" 5- reg: physical base address and length of the controller's registers 6- #pwm-cells: should be 3. See pwm.txt in this directory for a description of 7 the cells format. The only third cell flag supported by this binding is 8 PWM_POLARITY_INVERTED. 9- clocks: phandle to the PWM source clock 10 11Example: 12 13pwm1: pwm@d8220000 { 14 #pwm-cells = <3>; 15 compatible = "via,vt8500-pwm"; 16 reg = <0xd8220000 0x1000>; 17 clocks = <&clkpwm>; 18}; 19
