Nor MDIO busses and Ethernet PHYs. ACPI is missing a lot of support for basic elements of networking. I guess this is because it expects firmware in the NIC to be controlling these parts, not Linux. > > As soon as GPIOs and I2C busses are involved device trees are so much > better than ACPI Yes, ACPI has along way to go before it is usable for SoCs with integrated Ethernet.
