It's now possible to have the DW XPCS device defined as a standard platform device for instance in the platform DT-file. Although that functionality is useless unless there is a way to have the device found by the client drivers (STMMAC/DW *MAC, NXP SJA1105 Eth Switch, etc). Provide such ability by means of the xpcs_create_fwnode() method. It needs to be called with the device DW XPCS fwnode instance passed. That node will be then used to find the MDIO-device instance in order to create the DW XPCS descriptor. Note the method semantics and name is similar to what has been recently introduced in the Lynx PCS driver. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: David S.
