[PATCH v3 0/8] Enable video decoder & encoder for MT8189

[Kyrie Wu]

This series have the follow changing:
Firstly add mt8189 video decoder compatible, profile and level to support
MT8189 kernel driver.
Secondly fix some bugs, including vp 4K profile2 and media device node
number bug.
Lastly, add mt8189 video encoder compatible.

This series has been tested with MT8189 tast test.
Encoding and decoding worked for this chip.

Patches 1-2 Add decoder compatible.
Patches 3 Add profile and level supporting.
Patches 4 Add core-only VP9 decoding supporting.
Patches 5-6 fix some bugs.
Patches 7-8 Adds encoder compatible.

[PATCH v3 1/8] dt-bindings: media: mediatek: decoder: Add MT8189 mediatek,vcodec-decoder

[Kyrie Wu]

Add compatible for video decoder on MT8189 platform. Compared with
former ICs, the MT8189 decoder use iommu to instead of smmu, and
use scp architecture, the frequency is only 406MHZ, and cannot reach
more than 700MHZ. At the same time, the decoder supports the vp9
decoding protocol for the first time in single IC.

[PATCH v3 2/8] media: mediatek: vcodec: add decoder compatible to support MT8189

[Kyrie Wu]

MT8189 is pure single core architecture. Support its compatible and
use `mtk_vdec_single_core_pdata` to initialize platform data.

[PATCH v3 5/8] media: mediatek: vcodec: fix vp9 4096x2176 fail for profile2

[Kyrie Wu]

The dram addr of vp9 decoder tile number, which use dram mode
to set tile information, may reach to 36bits for 4096x2176.
It needs to get the highest 4bit of tile buffer address to
set tile buffer address.

[PATCH v3 7/8] dt-bindings: media: Add MT8189 mediatek,vcodec-encoder

[Kyrie Wu]

Add MT8189 encoder compatible string to distinguish former ICs
MTK's. Compared with MT8196, the maximum resolution of MT8189
encoder is only 4K, and the fps is only 30, which cannot reach
the highest parameter of MT8196: level6.2, 8K@60fps.
Compared with MT8188, the level can only support 5.1, which is less
than 5.2 of MT8188. But the maximum bitrate is 100Mbps, which is twice
that of MT8188. And MT8189 could support NBM mode.
