You mean, "does this node define a bus".  If it doesn't, there
shouldn't be #a and #s; if it does, the binding should describe
what the addressing is.  #a = #s = 0 describes a bus without any
addressing; pretty unusual :-)

Yes please.  There's a good chance that it doesn't turn out to be
Linux-specific at all (after some modification, perhaps).
