Kernel-4.18.0-80.el8_vt8500-pw

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.txt 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>;
};
