Afaik, mostly yes. I've seen some in other places, although they were
never official.

It could either go in linux/sound/arm or you could write a more generic
omap driver (i.e. not tightly coupled to either your board or codec) and
place it in sound/soc/omap/, this would allow your work to be used on
other boards/platforms.

Yes, I would recommend this.
