It looks like whatever tree you're building from is missing this patch:
  
  ARM: ux500: Add DMA config bindings for MSP devices

Which is part of the initial reason I said this:

  "If this patch-set could go through ASoC as a whole, it would drive
  down the chance of a dependency mess. Vinod has already provided
  Acks for his parts, so it's just between you two Linus and Mark."

But in Mark's defence, I also tentatively said this:

  "I'm not aware of any dependencies on the ARM changes. I haven't
  tested the arch/arm and sound/soc adaptions orthogonally, but I
  _think_ the right decisions should be made depending on the
  information passed from platform/dt code."

But this error seems strange, as I thought we were still passing the
MSP stuff as AUXDATA for this very reason i.e. lack of DMA support. So
I assumed that the MSP driver(s) would take the platform data
route. At least until the AUXDATAs have been removed, which was my
next step.
