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};
