| 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. Number of cells being used to specify PWM property. |
| First cell specifies the per-chip index of the PWM to use, the second |
| cell is the period in nanoseconds and bit 0 in the third cell is used to |
| encode the polarity of PWM output. Set bit 0 of the third in PWM specifier |
| to 1 for inverse polarity & set to 0 for normal polarity. |
| - clocks: phandle to the PWM source clock |
| |
| Example: |
| |
| pwm1: pwm@d8220000 { |
| #pwm-cells = <3>; |
| compatible = "via,vt8500-pwm"; |
| reg = <0xd8220000 0x1000>; |
| clocks = <&clkpwm>; |
| }; |
