Heiner Kallweit 72d8b4fdbf net: dsa: mv88e6xxx: support in-band signalling on SGMII ports with external PHYs
If an external PHY is connected via SGMII and uses in-band signalling
then the auto-negotiated values aren't propagated to the port,
resulting in a broken link. See discussion in [0]. This patch adds
this propagation. We need to call mv88e6xxx_port_setup_mac(),
therefore export it from chip.c.

Successfully tested on a ZII DTU with 88E6390 switch and an
Aquantia AQCS109 PHY connected via SGMII to port 9.

Andrew Lunn 2defda1f4b net: dsa: mv88e6xxx: Add support for SERDES on ports 2-8 for 6390X
The 6390X family has 8 SERDES interfaces. When ports 9 and 10 are not
using all their SERDES interfaces, the unused ones can be assigned to
ports 2-8. Add support for interrupts from SERDES interfaces connected
to these lower ports.

Andrew Lunn 4382172fa7 net: dsa: mv88e6xxx: Add SERDES phydev_link_change for 6352
The 6352 family has one SERDES interface, which can be used by either
port 4 or port 5. Add interrupt support for the SERDES interface, and
report when the link status changes.

Andrew Lunn 734447d4ed net: dsa: mv88e6xxx: Re-setup interrupts on CMODE change.
When a port changes CMODE, the SERDES interface being used can change.
Disable interrupts for the old SERDES interface, and enable interrupts
on the new.

Andrew Lunn efd1ba6af9 net: dsa: mv88e6xxx: Add SERDES phydev_mac_change up for 6390
phylink wants to know when the MAC layers notices a change in the
link. For the 6390 family, this is a change in the SERDES state.

Add interrupt support for the SERDES interface used to implement
SGMII/1000Base-X/2500Base-X. This is currently limited to ports 9 and
10. Support for the 10G SERDES and other ports will be added later,
building on this basic framework.

Andrew Lunn 07ffbd74d1 net: dsa: mv88e6xxx: 6390 vs 6390X SERDES support
The 6390 has two SERDES interfaces, used by ports 9 and 10.  The 6390X
has eight SERDES interfaces. These allow ports 9 and 10 to do 10G. Or
if lower speeds are used, some of the SERDES interfaces can be used by
ports 2-8 for 1000Base-X.

Andrew Lunn cda9f4aae3 net: dsa: mv88e6xxx: Get mv88e6352 SERDES statistics
Add support for reading the SERDES statistics of the mv88e8352, using
the standard ethtool -S option. The SERDES interface can be mapped to
either port 4 or 5, so only return statistics on those ports, if the
SERDES interface is in use.

The counters are reset on read, so need to be accumulated. Add a per
port structure to hold the stats counters. The 6352 only has a single
SERDES interface and so only one port will using the newly added
array. However the 6390 family has as many SERDES interfaces as ports,
each with statistics counters. Also, PTP has a number of counters per
port which will also need accumulating.

At the same time, ensure that relative header inclusions are separated

The mv88e6390X family has 8 SERDES lanes. These can be used for 2
10Gbps ports, ports 9 or 10. If these ports are used at slower speeds,
the SERDES lanes become available for other ports for 1000Base-X.
