-MediaTek display PWM controller
-
-Required properties:
- - compatible: should be "mediatek,<name>-disp-pwm":
-   - "mediatek,mt2701-disp-pwm": found on mt2701 SoC.
-   - "mediatek,mt6595-disp-pwm": found on mt6595 SoC.
-   - "mediatek,mt8167-disp-pwm", "mediatek,mt8173-disp-pwm": found on mt8167 SoC.
-   - "mediatek,mt8173-disp-pwm": found on mt8173 SoC.
- - reg: physical base address and length of the controller's registers.
- - #pwm-cells: must be 2. See pwm.yaml 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.
- - pinctrl-names: Must contain a "default" entry.
- - pinctrl-0: One property must exist for each entry in pinctrl-names.
-   See pinctrl/pinctrl-bindings.txt for details of the property values.

-Example:
-	pwm0: pwm at 1401e000 {
