+Mediatek Video Codec
+
+Mediatek Video Codec is the video codec hw present in Mediatek SoCs which
+supports high resolution encoding functionalities.
+
+Required properties:
+- compatible : "mediatek,mt8173-vcodec-enc" for encoder
+- reg : Physical base address of the video codec registers and length of
+  memory mapped region.
+- interrupts : interrupt number to the cpu.
+- mediatek,larb : must contain the local arbiters in the current Socs.
+- clocks : list of clock specifiers, corresponding to entries in
+  the clock-names property.
+- clock-names: encoder must contain "venc_sel_src", "venc_sel",
+- "venc_lt_sel_src", "venc_lt_sel".
+- iommus : should point to the respective IOMMU block with master port as
+  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
+  for details.
+- mediatek,vpu : the node of video processor unit
+
+Example:
+vcodec_enc: vcodec@0x18002000 {
+    compatible = "mediatek,mt8173-vcodec-enc";
+    reg = <0 0x18002000 0 0x1000>,    /*VENC_SYS*/
