I would recommend continuing to sort out how this works within the 
kernel before fixing things in DT. Something like this needs to be a 
core binding in the DT spec.

Also, you should CC some ARM, Ltd. folks like Mark R and Lorenzo. 
There's been some discussion in the past how to describe the DMA master 
side of the bus topology.
