++Mediatek display PWM controller
++
++Required properties:
++ - compatible: should be "mediatek,<name>-disp-pwm"
++   - "mediatek,mt8173-disp-pwm": found on mt8173 SoC
++   - "mediatek,mt6595-disp-pwm": found on mt6595 SoC
++ - reg: physical base address and length of the controller's registers
++ - #pwm-cells: must be 2. See pwm.txt in this directory
++   for a description of the cell format
++ - clocks: phandle and clock specifier of the PWM reference clock
++ - clock-names: must contain the following
++   - "main": clock used to generate PWM signals
++   - "mm": sync signals from the modules of mmsys
++
++Example:
++	pwm0: pwm@1401e000 {
++		compatible = "mediatek,mt8173-disp-pwm",
++			     "mediatek,mt6595-disp-pwm";
++		reg = <0 0x1401e000 0 0x1000>;
++		#pwm-cells = <2>;
++		clocks = <&mmsys MM_DISP_PWM026M>,
++			 <&mmsys MM_DISP_PWM0MM>;
++		clock-names = "main",
++			      "mm";
++	};
