On the other hand it's a problem that several devices have so we should
be able to factor out the interface matching so it should have at least
some of the code in one of the frameworks, dmaengine would seem natural
too me too but apparently audio is about the only user of cyclic DMA so
IIRC the DMA guys were pushing back on doing it there.
