This is connected to the (another) Marvell 88EA1512. I mentioned in the
earlier patch for sgmii_phy0 that you dropped the reset-assert-us.

Unless there was a reason for that, I suspect you want to add it here
too.

Otherwise the description matches the bit of schematic I have access to.

Thanks,
Andrew
