Yeah, bunch of different folks wrote the drivers, so lots of entries.
Pretty much all as you've done here, authors are responsible for the
individual components and Emil is the platform maintainer but
responsible for most drivers.

Do you need any feedback dt wise on the RFC, or is it too likely that
we'll both waste our breath if the DRM folks don't approve of your
approach for the rest of this series?
