I'd rather not just export 27 omap specific functions for the dmtimer to the
drivers knowing what kind of mess it will be.. There's some work happening
to make the dmtimer more generic, so for those parts we should have a solution
soonish.

Yeah and the tidspbridge should use the remoteproc which seems to be missing
from the TODO file. Anyways, the pending dmtimer work should not impact fixing
the other issues from development point of view.
