Subject[PATCH 0/6] mvneta: SGMII-based in-band link state signaling

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.
