Hisilicon PWM controller Required properties: -compatible: should contain one SoC specific compatible string The SoC specific strings supported including: "hisilicon,hi3516cv300-pwm" "hisilicon,hi3519v100-pwm" - reg: physical base address and length of the controller's registers. - clocks: phandle and clock specifier of the PWM reference clock. - resets: phandle and reset specifier for the PWM controller reset. - #pwm-cells: Should be 3. See pwm.txt in this directory for a description of the cells format. Example: pwm: pwm@12130000 { compatible = "hisilicon,hi3516cv300-pwm"; reg = <0x12130000 0x10000>; clocks = <&crg_ctrl HI3516CV300_PWM_CLK>; resets = <&crg_ctrl 0x38 0>; #pwm-cells = <3>; };
