you mean something like this is enough:

Documentation/devicetree/bindings/display/mediatek/mediatek,disp.txt

   argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
   for details.

+Optional properties:
+- port (input and output) see ../../media/video-interfaces.txt
+
 Examples:

Documentation/devicetree/bindings/display/mediatek/mediatek,dpi.txt:

 Optional properties:
 - pinctrl-names: Contain "default" and "sleep".
+- port: Input port node with endpoint definition, this can be connected to <chipid>-disp-pwm

 Example:

should i link to pwm/pwm-mtk-disp.txt in doc?
