I suspect some of the function names in your description here are
incorrect :) Another option is to provide a callback in the private data
passed to the DMA driver which the DMA driver can call at the
appropriate point during setup.

Someone will presumably also need to take care of the same things in the
other S3C DAI drivers too, though it should be possible to arrange
things so that can be done seperately.
