The examples will looks like following:

pwm0: pwm0 at 1e610000 {
  compatible = "aspeed,ast2600-pwm";
  reg = <0x1e610000 0x8>;
  #pwm-cells = <3>;
  #address-cells = <1>;
  #size-cells = <0>;
  pinctrl-names = "default";
  pinctrl-0 = <&pinctrl_pwm0_default>;
  clocks = <&syscon ASPEED_CLK_AHB>;
  resets = <&syscon ASPEED_RESET_PWM>;
  status = "disabled";
};

pwm1: pwm1 at 1e610010 {
  compatible = "aspeed,ast2600-pwm";
  reg = <0x1e610010 0x8>;
  #pwm-cells = <3>;
  #address-cells = <1>;
  #size-cells = <0>;
  pinctrl-names = "default";
  pinctrl-0 = <&pinctrl_pwm1_default>;
  clocks = <&syscon ASPEED_CLK_AHB>;
  resets = <&syscon ASPEED_RESET_PWM>;
  status = "disabled";
};
...

Thanks
