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.
