Yoshihiro, sorry for this. If not for my complaints, your proposal could
already be merged (maybe). Anyway, I think the best solution would be
to implement phylink properly, even for cases that are not relevant for
your board*, but this would take a non-trivial amount of time, so
I will understand if you want to stick with phylib.

* Altough you don't use fixed-link or SFP on your board, I think it
  should be possible to test it somehow if you implemented it...
  For example, I have tested fixed-link between SOC and switch SerDes
  by configuring it in device-tree on both sides.
