I want to get Martyn's feedback on this, as it's adding a new feature to
the subsystem that he's going to have to maintain.
Sorry about the *really* late reply, loads of emails some how missed my
periodic search of the mailing list.
I'm happy with the addition of DMA, just not sure whether it's worth
adding an extra device file just to handle DMA. Could the user space
application not just use the control device?
