Tue Jul 6 23:21:47 PDT 2021


Decoder will use component framework to manage hardware, it is big
difference with encoder.

+Mediatek Video Decoder
+
+Mediatek Video Decoder is the video decode hw present in Mediatek SoCs which
+supports high resolution decoding functionalities. With component framework
+require master and component node properties:
+
+Required properties(no component framework):
+- compatible : must be one of the following string:
+  "mediatek,mt8173-vcodec-dec" for MT8173 decoder.
+  "mediatek,mt8183-vcodec-dec" for MT8183 decoder.
+- reg : Physical base address of the video decoder 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: must contain "vcodecpll", "univpll_d2", "clk_cci400_sel"
+  "vdec_sel", "vdecpll", "vencpll", "venc_lt_sel", "vdec_bus_clk_src".
