Kernel-4.18.0-80.el8_pwm-sun4i

Allwinner sun4i and sun7i SoC PWM controller

Required properties:

• compatible: should be one of:
  • “allwinner,sun4i-a10-pwm”
  • “allwinner,sun5i-a10s-pwm”
  • “allwinner,sun5i-a13-pwm”
  • “allwinner,sun7i-a20-pwm”
  • “allwinner,sun8i-h3-pwm”
  • “allwinner,sun50i-a64-pwm”, “allwinner,sun5i-a13-pwm”
  • “allwinner,sun50i-h5-pwm”, “allwinner,sun5i-a13-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.
• clocks: From common clock binding, handle to the parent clock.

Example:

pwm: pwm@1c20e00 {
    compatible = "allwinner,sun7i-a20-pwm";
    reg = <0x01c20e00 0xc>;
    clocks = <&osc24M>;
    #pwm-cells = <3>;
};
