Hi Paul

I would so you are doing it all wrong for the reset GPIO.

Well, you are adding a device tree binding, which needs to be
supported forever. This is going to make things messy in the future
when you do such a cleanup that you follow the PHY binding, in that
you have to handle both what you add here, and the official PHY
binding.

I would prefer that for the moment, you drop the PHY binding patches
in this series. That is what i object to the most. Adding an MDIO
driver and using the standard PHY driver for this PHY is all
internal. You can change that anytime. But adding a binding means an
ABI.
