I'm not sure if I can agree with that.

The core idea befind the dma engine framework seams to be to statically
assign dma channels to device drivers. I think that the channels should
be dynamically assigned.

Imo writing an alternative implementation is much easier than hacking that
into the existing framework. Especially since the existing framework has
only one backend driver and only one user.
