I would split this commit in two:
1. drm/mediatek: dsi: Support dynamic connector selection 2. drm/mediatek: Support DSI on MT8188 VDOSYS0
Where the first one sets up the mtk_dsi driver for .encoder_index(), and where the second one is a one-liner simply adding `{0, DDP_COMPONENT_DSI0},` to the MT8188 main routes array.
The reason is that if you split it like that, whoever reads the commit history will immediately understand how to add dynamic connector selection to a MTK DRM driver, and how to perform the SoC-specific connection....
Please!
Thanks, Angelo
