Yes, this is a board specific setup, just as non-dt does currently.
Different boards may have different setting.

I can do it.
This patch series was made based on Mark's sound-2.6 tree.
Do you want this one go through mxs tree and other three go through Mark's tree?
I'm thinking maybe it would be better go through one tree(Mark's or Yours) since
without this one the saif record still can not work.
Maybe go through yours may save some conflicts.
What's your suggestion?
