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.

Why?
As mentioned in other threads: select for DSI controllers, depends on -
for DSI peripherals.

Because the driver otherwise uses select, as mentioned. An attempt to
use "depends on" results in a circular dependency.

Please feel free to find a better solution, preferrably one that does
not result in a circular dependency.

OK, I was blind. Next time please provide error message from recursive
dependency, it should give better hint what is going on.
Now I understand why Sean posted the patch changing "depends on" to
select :)
