There's pretty good support for the style that was first in the s3c2412,
which I belive was the last of the two-channel I2S blocks.

I've run an WM8530 in slave mode on an S3C6410, so it was working last
time I tried it. It was one of the test cases to check the code out before
it was submitted.

What we don't yet have in the mainline is any of the 'V40' which are for
5.1 style I2S links (multiple tx paths).
