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.

Well of course it will remain in the per-device bindings.  But just
because these are in different per-device bindings doesn't mean we
can't *try* to use consistent property names for similar things...

Sure, if those properties do exactly the same thing, identical
names are a good thing.  Until we're reasonably certain that this
is a good way to do things I'd rather people experiment a bit
instead of all cluster around a random thing that would be labeled
"de facto standard".
