We should co-ordinate better on this, if it's to become a
convention...

That means we shouldn't coordinate on this, right?

Heh.  Either one is kind of ugly, I'll grant you.

But, many SoCs do have a notion of device "number", which is relevant
for programming other general control registers in places.  We need to
encode it somehow, and it would be good to have a consistent way of
doing it.

I'm not convinced there isn't a more direct way to represent
the relevant relationships.

Either way, we don't have enough experience with this stuff
yet to know what works well and what doesn't (at least, I
don't, and I haven't seen any evidence that others do); so
I'd prefer to keep this in per-device bindings for now; it
should be there anyhow, but once we do have experience with
it we could do some recommendation.
