Sorry, misread your email :-). I have some patches which still need a
bit of work, but provide SoC audio support using i2s on the ep93xx. They
are based on the work by Chase and Lennert.
If you are interested, I can generated some patches against for you. You
will probably have to hack around with them a bit to get them going.
