Sure, I'm not planning to spam alsa-devel however the switch to dmaengine PCM
for AM335x/AM447x needs the edma patches, otherwise it is not going to work.
AFAIK I have not sent patch to edma as of now so I have no idea how long it
takes to get stuff in (the good thing is that the edma part does not touch DT,
which is alone can reduce the number of iterations).
Anyway, what I can - and already did is:
Reorder the ASoC patches and I can leave out the switch to dmaengine PCM patch
for davinci-mcasp for now. The edma-pcm and the other patches for McASP can go
in right away (I will not add the edma-pcm to the Makefile/Kconfig to avoid
issues).

I will detach the edma stuff and follow it up outside of alsa-devel.

The only thing I'm afraid off is that it is going to take two release cycle to
get this in: first cycle edma part, next cycle for the ASoC to switch to use
the edma-pcm.
