Currently the fixed-link DT binding is pre-configured and cannot be changed in run-time. This means the cable unplug events are not being detected, and the link parameters can't be negotiated. The following patches are needed when mvneta is used in fixed-link mode (without MDIO). They add an API to of_mdio for updating the fixed_phy status, and use that API in the mvneta driver when parsing the SGMII in-band status. Signed-off-by: Stas Sergeev
