So, this basically seems fine but I'm looking at this code and I'm not
really seeing a huge amount of OMAP specificness here.  Why is this an
OMAP driver and not something more generic - can't we have other HDMI
controllers offering the same interface?  There's a few serial numbers
that would need filing off but since the ASoC driver is basically just
interface matching and not talking to the hardware it looks like it
ought to be usable by more than just OMAP.
