+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"
+ "hisilicon,hi3559v100-shub-pwm"
+ "hisilicon,hi3559v100-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.yaml 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>;
+ };
