Rewrite the textual description for the WonderMedia PWM controller
as YAML schema, and switch the filename to follow the compatible
string.

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. See pwm.yaml in this directory for a description of

  the cells format. The only third cell flag supported by this binding is

  PWM_POLARITY_INVERTED.

- clocks: phandle to the PWM source clock



Example:



pwm1: pwm@d8220000 {

	#pwm-cells = <3>;

	compatible = "via,vt8500-pwm";

	reg = <0xd8220000 0x1000>;

	clocks = <&clkpwm>;

};
