The implicit fallback mechanism for searching the whole MDIO bus for at least one PHY has been gone with the following commit b882005a18de ("drivers/net/fec: phy_init: remove redundant logic"). This lead to the Ethernet driver erroring out as follows:
Net: Could not get PHY for FEC0: addr -19 eth-1: fec@400d1000 Colibri VFxx # dhcp Could not get PHY for FEC0: addr -19 Could not get PHY for FEC0: addr -19 Could not get PHY for FEC0: addr -19 Could not get PHY for FEC0: addr -19 No ethernet found. Could not get PHY for FEC0: addr -19 Colibri VFxx #
This commit adds an explicit PHY node which makes it work again.
