Just one side comment (I'm fine with either choice, just for your
information). Recently I have reviewed at24 patch which adds a
property for getting MAC offset and my reseach ends up with the naming
pattern mac-offset (as many others are doing this way). So, perhaps in
your case it might make sense to do that way? Anyway, it's a matter of
a (bit of a) chaos in DT bindings, whatever you decide users will live
with.
