Yes, I think we will have to, otherwise we can't ensure we have cross-
compatibility between different DMA engine implementations.

We already have platforms where we have peripheral drivers making use of
several different DMA engine implementations, so nailing this down now,
before the number of DMA engine implementations increases still further
is definitely something that needs doing.
