[PATCH v4 0/9] Add support for multiple chips

Thu Nov 24 04:38:50 PST 2022

Changes since v3:
- Rebase on linux-next.
- In the file "mtk-mdp3-m2m.c", use the limited resolution defined by
  each platform to replace the default format.
- Add platform ID in driver data, and refine shared memory structure preprocessing.
- Simplify the way to get mutex ID in function "mdp_path_subfrm_require".

Changes since v2:
- Depend on :
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=687004
- Split the shared memory header(mtk-img-ipi.h) by preprocessing instead, and
  classify the generic parts into "mtk-mdp3-type.h", and move
  chip-specific parts to"mt8183/mdp3-comp-mt8183.h".

Changes since v1:
- Depend on :
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=687004
- For hardware-specific structures in the shared memory header(mtk-img-ipi.h),
  split the relevant functions and structure definitions.

Hi,

To support multiple chips, a chip configuration header file needs to be created
and the relevant information split and moved into it.
