Subject: [PATCH v3 0/6] Add support for MT8196 video encoder

This patch series add support for MT8196 video encoder.
patch 1~3: Add a new encoder driver interface for new VCP firmware.
patch 4~6: Add MT8196 encoder driver platform data.

About adding new driver support, the v4l2-compliance report shows:
"Total for mtk-vcodec-enc device /dev/video3: 47, Succeeded: 46, Failed: 1, Warnings: 0"
The 1 Failed case is not caused by current patch set.

This patch set depends on "media: mediatek: vcodec: support video decoder in mt8196"[1]

[1] https://patchwork.linuxtv.org/project/linux-media/list/?series=15232

Change in v3:
 - Add venc rc buffer alloc failure error handling.
 - Add mediatek,vcp property definition in dt-bindning.

Change in v2:
 - Add support for VCP encode process.
 - Add MT8196 encoder driver platform data.
 - Rebase encoder patch onto decoder's patch set.
 - Fix some review comments in v1.

Irui Wang (6):
  media: mediatek: encoder: Add a new encoder driver interface
  media: mediatek: encoder: Add support for common firmware interface
  media: mediatek: encoder: Add support for VCP encode process
  media: mediatek: encoder: Add a new platform data member
  dt-bindings: media: Add MT8196 mediatek,vcodec-encoder
  media: mediatek: encoder: Add MT8196 encoder compatible data
