Quite obviously the driver depends on DRM_MIPI_DSI. We can not use "depends" since the driver configuration uses "select", so we'll have to select the missing dependency instead.

You can't mix depends and select for the same symbol, or all hell breaks loose. So needs a depends on DRM_MIPI_DSI instead. With that changed:
Yes, that is why I used select, not depends, as explained. "depends" causes a circular dependency.
I missgrepped, it's already chaos, so select should be perfectly fine. Well as fine as Kconfig can be.
Thanks for circling back, I've pushed the patch to -misc-next with your R-b.
