Grant and I are the only two active users of I2S and we're passing
patches to each other.  I don't have I2S completely fixed yet.

I'll post a series today that reorgs things to make my real patches
easier to apply. The series has already been posted on linux-ppc and
ack'd by Grant. He want it to go in via the ALSA trees. It is a
passive change that splits mpc5200_i2s.c into multiple files and
breaks out the DMA code. I need to rename a couple of globally visible
functions before posting it again.

My real patches fix up i2s and implement ac97.
