    Hi Gibbs,

    Sorry for the delay in response.

    As far as a phy is concerned, the only things which should to be changed is the phy node present inside the MDIO node of CPSW2G node and bus frequency property of the same MDIO node. For reference for ksz9031 phy, see [PSDK-LINUX-INSTALL-PATH]/Documentation/devicetree/bindings/net/micrel-ksz90x1.txt. In general, the references for phy is present in [PSDK-LINUX-INSTALL-PATH]/Documentation/devicetree/bindings/net folder for multiple vendors and their products.

    In config, make sure to enable CONFIG_MICREL_PHY and CONFIG_NET_VENDOR_MICREL by setting it to "y".

    Regards,
    Tanmay
