Hmm, that doesn't sound right.
So, I'm no longer sure that unifying i2s and awacs will work right, I
think factoring out the DMA code and pulling it in as dependency is
the least painful way here. That said, I hereby drop my reservations
about putting the gpio stuff into i2s, I think you're right about
having all that in one place. I would still like the sound-objects
parser to be mostly abstract so it can be used by both i2s and awacs.
