Jackie:
Lars is correct -- the audio portion of the ADV7611 doesn't exist in our tree yet.
We (Lars) have been helping (minimally) someone who has a 4.0.0 kernel fork at:
https://github.com/Vodalys/linux-veobox/commits/veobox/sound
that recently added support for the ADV7611 audio side.(link above)
the driver still needs a little work, but it might be easier to start with something that at least works on their platform (which looks like is iMx.6). They are working on putting things together, as a real patch, but they are away from keyboards the next few weeks.
