+Mediatek Video Codec
+
+Mediatek Video Codec is the video codec hw present in Mediatek SoCs which
+supports high resolution encoding and decoding functionalities.
+
+Required properties:
+- compatible : "mediatek,mt8173-vcodec-enc" for MT8173 encoder
+ "mediatek,mt8183-vcodec-enc" for MT8183 encoder.
+ "mediatek,mt8173-vcodec-dec" for MT8173 decoder.
+- 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", decoder must contain "vcodecpll",
+ "univpll_d2", "clk_cci400_sel", "vdec_sel", "vdecpll", "vencpll",
+ "venc_lt_sel", "vdec_bus_clk_src".
+- iommus : should point to the respective IOMMU block with master port as
+ argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
+ for details.
+One of the two following nodes:
+- mediatek,vpu : the node of the video processor unit, if using VPU.
+- mediatek,scp : the node of the SCP unit, if using SCP.
+
