So you mean drivers/of/of_mdio.c:of_mdiobus_child_is_phy() has a white list like: "brcm,40nm-ephy" "marvell,88E1111", "marvell,88e1116", "marvell,88e1118", "marvell,88e1149r", "marvell,88e1310", "marvell,88E1510", "marvell,88E1514", "moxa,moxart-rtl8201cp", Yes, that would work. We should also update the binding documentation to limit what is legal in the compatible string. Andrew
