Probably you misunderstand Arnd word.

"From the statements made so far, I can see no clear policy that we can
apply to everyone. My take on this is that for any work I spend on
multiplatform kernel, I concentrate on the DT-based board files and
get them to work together first, but leave it up to the individual
subarch maintainers whether they want to add other board files into
the mix."

It doesn't mean add new feature to non-DT board. don't add new board file.

In this case, DRM is not yet ready to support DT.

Okay, you can just drop this patches. but please note that this
patches are posted at Mar 13 before you decide.
