Subject: [PATCH v2, 04/14] dt-bindings: media: mtk-vcodec: Separate video encoder and decoder dt-bindings
Decoder will use component framework to manage hardware, it is big
difference with encoder.
Signed-off-by: Yunfei Dong <yunfei.dong@...iatek.com>
---
v2: Remove useless code for this patch.

+Mediatek Video Encoder
+
+Mediatek Video Encoder is the video encode hw present in Mediatek SoCs which
+supports high resolution encoding functionalities.
+
+Required properties:
+- compatible : must be one of the following string:
+ "mediatek,mt8173-vcodec-enc-vp8" for mt8173 vp8 encoder.
+ "mediatek,mt8173-vcodec-enc" for mt8173 avc encoder.
+ "mediatek,mt8183-vcodec-enc" for MT8183 encoder.
+ "mediatek,mt8192-vcodec-enc" for MT8192 encoder.
+- reg : Physical base address of the video encoder 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: avc encoder must contain "venc_sel", vp8 encoder must
+ contain "venc_lt_sel".
+- iommus : should point to the respective IOMMU block with master port as
+ argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml
+ for details.
+- dma-ranges : describes the dma address range space that the codec hw access.
+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.
