+Mediatek Video Decoder With Component
+
+Mediatek Video Decoder is the video decode hw present in Mediatek SoCs which
+supports high resolution decoding functionalities. Required master and
+component node properties:
+
+Master properties:
+- compatible :
+ "mediatek,mt8192-vcodec-dec" for MT8192 decoder.
+- reg : Physical base address of the video decoder registers and length of
+ memory mapped region.
+- iommus : should point to the respective IOMMU block with master port as
+ argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
+ for details.
+- mediatek,scp : the node of the SCP unit, if using SCP.
+
+component properties(core and lat):
+- compatible(core) : "mediatek,mtk-vcodec-core" core hardware decoder
+ "mediatek,mtk-vcodec-core" for core hardware decoder.
+- compatible(lat) : "mediatek,mtk-vcodec-lat" lat hardware decoder
+ "mediatek,mtk-vcodec-lat" for lat hardware decoder.
+- reg : Physical base address of the video decoder registers and length of
+ memory mapped region.
+- interrupts : interrupt number to the cpu.
+- clocks : list of clock specifiers, corresponding to entries in
+ the clock-names property.
+- clock-names: 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.
+- dma-ranges : describes how the physical address space of the IOMMU maps
+ to memory.
