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.
