I guess you are referring to this: [1]?

If so, the last version I could find is a year old now. Is anyone still
working on this?

I understand, that the generic approach is the one we want to have, but
does this really mean adding PHY led configuration via DT to existing
drivers (that already use DT properties for LED modes) is not accepted
anymore, even if the new API is not yet in place?

If anyone (Marek?) would be willing to revive this series, I could maybe
try to find some spare time to rework the mscc PHY LED configuration on
top of this and do some tests.
