I put it to you that DPCM in mainline is incomplete and nonfunctional
as it currently stands.  Moreover, it requires either those who know
that code to continue to develop it, or someone else who understands
the direction that this code is supposed to go picks up to complete it.

I'd be most distressed if it were far off working; it's close enough to
the out of tree code I've worked with and I know there were drivers in
progress when it was submitted.  We've certainly had at least one bug
fix from the out of tree users, I'd be surprised if we had anything more
substantial than bitrot in the current code.

Right, so, I've looked at this again today, and I've sort-of got it
working.

I'm not so sure about that:

Russell, I'm just back from holiday now and have done a quick re test on
Haswell. I can see the correct DAPM path and DPCM state as expected for
Haswell, but let me get through my Inbox today and I'll see where we
have some differences tomorrow.
