So, I tried to apply this to my topic/interface branch (which is where
I'm keeping stuff for merge into other trees) but that won't fly due to
the internal.h change.  What I might do to resolve the merge issues is
to make a commit with the new regmap.h changes alone.  This won't help
in terms of actually running things but it'll keep things buildable
which is more achievable.

Anyway, thanks for doing this - there's a bunch of other devices that
need this.
