Subject: [PATCH v12 0/4] Add mmsys and mutex support for MDP

Change since V11:
- Rebase on v5.17-rc6.

[2]: https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/commit/?h=v5.17-next/soc&id=831785f0e5b919c29e1bc5f9a74e9ebd38289e24

Change since v10:
- For some ISP application scenarios, such as preview and recording
  at the same time.
  The routing table needs to be discarded, and the calculation result
  on the SCP side is used to write a suitable mux setting for
  1 input and 2 output.
- Adjust the GCE client register parsing method to avoid redundant warning logs.

Change since v9:
- Add API for MDP getting mutex mod.

Hi,

This patch splits mmsys and mutex settings from Media Data Path 3 (MDP3),
and original mailling list list below:
https://patchwork.kernel.org/project/linux-mediatek/cover/20211201095031.31606-1-moudy.ho@mediatek.com/
Corresponding settings and interfaces are added for MDP operation in the
mmsys and mutex drivers, which increases the independence of the modules

Moudy Ho (4):
  soc: mediatek: mmsys: add CMDQ write register function
  soc: mediatek: mmsys: add support for ISP control
  soc: mediatek: mutex: add support for MDP
  soc: mediatek: mutex: add functions that operate registers by CMDQ
