Hi Jeremy

What exactly does NXP0006 represent? An XGMAC MDIO bus master? Some
NXP MDIO bus master? An XGMAC Ethernet controller which has an NXP
MDIO bus master? A cluster of Ethernet controllers?

Is this documented somewhere? In the DT world we have a clear
documentation for all the compatible strings. Is there anything
similar in the ACPI world for these magic numbers?

Thanks
