I wrote the only i2s driver I am aware of, but none of Lennert's
ep93xx audio support was integrated into mainline, so my i2s part was
left behind too. As for the code itself, it's been a few years since
I've even seen it. I probably have a backup somewhere locally if it's
needed, but I think there's a big patch on this mailing list too. You
would probably find it around this time in 2007.
