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.yaml 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};
