From: Xinlei Lee <xinlei.lee@mediatek.com>
Base on the branch of Linux-next/master.
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.

Separate this patch into two patches. One is adding edge_cfg_in_mmsys, and another one is adding mt8186 dpi support. I think the default value in mmsys (single edge) should work for some display so that mmsys hardware use single edge for default value. So I need you to describe more information why we need dual edge. > > Co-developed-by: Jitao Shi <jitao.shi@mediatek.com> > Signed-off-by: Jitao Shi <jitao.shi@mediatek.com> > Signed-off-by: Xinlei Lee <xinlei.lee@mediatek.com> > Reviewed-by: AngeloGioacchino Del Regno < > angelogioacchino.delregno@collabora.com> > Reviewed-by: Nílas F.
