Subject: [PATCH v7 00/12] Add support for multiple chips
Changes since v6:
- Rebase on media_stage tree
- Fix smatch error:
"drivers/media/platform/mediatek/mdp3/mdp_cfg_data.c:452
mdp_cfg_get_id_public() error: 'mdp_dev' dereferencing possible ERR_PTR()"
Changes since v5:
- Rebase on linux-next.
- Integrate the chip configuration into a source file called "mdp_cfg_data.c"
instead of a header file.
- Fix undefined reference to __udividi3 caused by patch [1/12].
- Fix parentheses issue reported by check script.
- Fix compilation and smatch errors
Changes since v4:
- Rebase on linux-next.
- Fix potential frame size overflow in "mtk-mdp3-regs.c".
- Fix OOB in MDP3 component clocks in "mtk-mdp3-comp.*".
- Reconfigure the shared memory between MDP3 kerenl and SCP.
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.
