Possibly so; I don't have access from this computer to my previous notes
on this topic.

I don't have a good feeling of how reusable this PCS IP truly is.
For example the XPCS gained DT bindings before I needed to customize the
lane polarity for its SJA1105 instantiation, so now I have to work with
and somehow adapt those.

If the PCS has a fixed mapping to that port then I suppose it can use
its OF node space without any extra overengineering. There should exist
ways to keep compatibility with this scheme even if there will be
efforts to have a reusable driver later.
