+* Mediatek Media Data Path
+
+Media Data Path is used for scaling and color space conversion.
+
+Required properties:
+  - compatible : should contain them as below:
+        "mediatek,mt8173-mdp"
+        "mediatek,mt8173-mdp-rdma"
+        "mediatek,mt8173-mdp-rsz"
+        "mediatek,mt8173-mdp-wdma"
+        "mediatek,mt8173-mdp-wrot"
+  - clocks : device clocks
+  - power-domains : a phandle to the power domain.
+  - mediatek,larb : should contain the larbes of current platform
+  - iommus : Mediatek IOMMU H/W has designed the fixed associations with
+        the multimedia H/W. and there is only one multimedia iommu domain.
+        "iommus = <&iommu portid>" the "portid" is from
+        dt-bindings\iommu\mt8173-iommu-port.h, it means that this portid will
+        enable iommu. The portid default is disable iommu if "<&iommu portid>"
+        don't be added.
+  - mediatek,vpu : the node of video processor unit
+
