I suspect that is not going to be easy. Last time i looked, the ACPI
standard had nothing about MDIO busses or PHYs. Marcin Wojtas did some
work in this area a while back for the mvpp2, but if i remember
correctly, he worked around this by simply not having a PHY when using
ACPI, and making use of a MAC interrupt which indicated when there was
link.
Whoever implements this first needs to be an ACPI expert and probably
needs to write it up and submit it as an amendment to the ACPI
standard.
