At the current moment it is not possible to set options with this format on ast2400/2500: mac { phy-handle = <&phy>; phy-mode = "rgmii"; mdio { #address-cells = <1>; #size-cells = <0>; phy: ethernet-phy@0 { compatible = "ethernet-phy-idxxxx.yyyy"; reg = <0>; }; }; }; The patch fixes it and gets possible PHYs and register them with of_mdiobus_register. Changes from v3: 1. add dt-bindings description of MDIO node and phy-handle option with example. Changes from v2: 1. change manual phy interface type check on phy_interface_mode_is_rgmii function. 2. add err_phy_connect label. 3. split ftgmac100_destroy_mdio into ftgmac100_phy_disconnect and ftgmac100_destroy_mdio. 4. remove unneeded mdio_np checks. Changes from v1: 1. split one patch into two.
