I guess we'll need a topic branch for the base enabling to merge to both
din and dign? I guess it'll need to include the stuff in
topic/intel-gen-to-ver too.

Shared stuff like this keeps being a problem with the separate dign
branch, especially when the only way to sync is to merge both din and
dign to drm-next and then backmerge to both.

BR,
Jani.
