My only concern, which I know the answer to I think, is shouldn't we
just have no default values here, and case in the right one for
omap5/dra74x and then dra72x in the future, etc, etc.  But we don't
know enough really to know if future SoCs will need a different
statement here, so it's good enough for now.
