Change since V16: - Rebase on v5.18-rc4 - Fix misplacement of definition "CONFIG_MTK_CMDQ" which caused compilation error when CMD is not supported. Change since V15: - Rebase on linux-next. - As suggested by Angelo, split common parts into independent functions to make functions more concise. - Based on safety considerations, increase the returned error number and message to facilitate error handling. Change since V14: - Rebase on linux-next. - Add new SOF and MOD table for general interface to integrate the requirement of different modules. - Remove unnecessary MOD structure. - By Rob Herring's suggestion, revise the description of "mediatek,gce-client-reg" in MUTEX dt-bindings. - Delete the redundant definition of MTK_MUTEX_ENABLE and modify corresponding function. Change since V13: - Rebase on linux-next tag:next-20220316 - Adjust the MUTEX MOD table structure and corresponding functions. - Adjust the definition style about 8183 MDP MOD. - Remove redundant definitions and enumerations. - Adjust the CMDQ operation in MUTEX to be backward compatible Change since V12: - Rebase on linux-next - Remove ISP related settings in MMSYS - Removed CMDQ operations previously used by MDP in MMSYS - Move mediatek MUTEX dt-binding path - Add additional property in MUTEX for CMDQ operations Change since V11: - Rebase on v5.17-rc6.

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 (6): soc: mediatek: mutex: add common interface for modules setting soc: mediatek: mutex: add 8183 MUTEX MOD settings for MDP dt-bindings: soc: mediatek: move out common module from display folder dt-bindings: soc: mediatek: add gce-client-reg for MUTEX dts: arm64: mt8183: add GCE client property for Mediatek MUTEX soc: mediatek: mutex: add functions that operate registers by CMDQ .../mediatek/mediatek,mutex.yaml | 14 +- arch/arm64/boot/dts/mediatek/mt8183.dtsi | 1 + drivers/soc/mediatek/mtk-mutex.c | 168 +++++++++++++++++- include/linux/soc/mediatek/mtk-mutex.h | 24 +++ 4 files changed, 205 insertions(+), 2 deletions(-) rename Documentation/devicetree/bindings/{display => soc}/mediatek/mediatek,mutex.yaml (82%)
