Subject: [PATCH v3 0/2] mvneta: SGMII-based in-band link state signaling

Hello.

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 fixed_phy that allows to update
status, and use that API in the mvneta driver when parsing
the SGMII in-band status.

There is also another implementation that doesn't add any API
and does everything in mvneta driver locally:
https://lkml.org/lkml/2015/3/31/327
I'll let people decide which approach is better.
No strong opinion on my side.
