So can you state why this would be needed? This is the RTL8211 ID,
right? Which should be autodetected via MDIO. Looking back in my inbox
you proposed this change before, for U-Boot, specifically, but I fail to
find a solution or explanation what really happens here. Two Renesas .dts
files have the same compatible, and the commit message talks about the
reset line there, is this related?
So can you please give some more background and explanation? That would be
part of a good commit message anyway ("why", not "what").
Cheers,
Andre
