I've heard of no such rule from the people I've been working with.  This
is an internal matter though, so I'll do some checking.

A Kconfig option is better than what's currently there, but yes I know
what you mean.  The phys are already part of the device tree, so I think
I'll add a compatible property as you suggested and add that to the
hw_info structure that the ethernet driver uses to init things.

Seems silly to carry this around in a data structure for a single use,
but I don't see another way of doing it while still making the
multiplatform thing happy.
