Changes since v6: 1. Different from other ICs, when mt8186 DPI changes the output format, the mmsys_base+400 register needs to be set to be valid at the same time. In this series, all the situations that mmsys need to be set up are perfected (not necessarily used in practice). 2. Put the value that controls the mmsys function in mtk-mmsys.h. 3. Encountered the sink ic switched between dual edge and single edge, perfected setting and clearing mmsys bit operations in mtk_dpi.c. Changes since v5: 1. Separate the patch that adds edge_cfg_in_mmsys from the patch that adds mt8186 dpi support. 2. Move the mmsys register definition to mmsys driver. Changes since v4: 1. This series of cancellations is based on the following patches: [1] Add MediaTek SoC(vdosys1) support for mt8195 https://patchwork.kernel.org/project/linux-mediatek/cover/20220711075245.10492-1-nancy.lin@mediatek.com/ [2] Add MediaTek SoC DRM (vdosys1) support for mt8195 https://patchwork.kernel.org/project/linux-mediatek/cover/20220804072827.22383-1-nancy.lin@mediatek.com/ 2. Added mtk_mmsys_update_bits function in mtk-mmsys.c; 3. MMSYS 0x400 register is modified to MT8186_MMSYS_DPI_OUTPUT_FORMAT; 4. Fix formatting issues. Changes since v3: 1. Fix formatting issues; 2. Modify the edge output control name & description; 3. Fix the threading problem. Changes since v2: 1. Modify key nouns in the description; 2. Add the label of jitao to Co-developed-by; 3. Macro definition address lowercase problem and function naming; 4. Add missing a description of this property in the mtk_dpi_conf. Change since v1: 1. Modify mt8186 compatiable location. 2. Modify MT8186_DPI_OUTPUT_FORMAT name. When MT8186 outputs dpi signal, it is necessary to add dual edge output format control in mmsys.
