Few users watch the dmesg log, But I totally see your point.

The problem I'm trying to address here is this: when I want to
reset the fec phy, I go look at existing devicetrees. Nearly
all of them use phy-reset-gpios, so that's what I'll use. But,
when I try to upstream the patch, the maintainer will tell me:
"no, that is deprecated, use this other method".

Is there a good solution you can think of which would point
the unwary developer to the correct phy reset method?
