No it isn't :-) .

That's what I get when I try looking at patches on a saturday before
coffee ;-) .

With the reset moving into the phy-node, the phy driver will trigger its
reset itself of course. The arc-mdio also request the reset-gpio as
optional, so the whole thing won't fail if te gpio is not present.

Sorry about the noise, the patch is correct obviously.
