Problem seems to be the notion that the proposed devicetree entry would not
describe the hardware, but its use. Not really sure I understand the problem,
as I would see the hardware description to be "A hardware device which is
compatible to and managed by the generic-uio driver". I would argue that
this _is_ a hardware description (if not, what is ?), but I am not the one
to make the call.

Turns out this is exactly what I need, and your post saves me the time
I would have spent writing essentially the same code and submitting it,
only to have it rejected.

Thanks a lot for digging this up!
