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>; };
