Subject: [PATCH v2 net 0/2] net: dsa: mv88e6xxx: fix marvell 6320/21 switch probing
As of commit de5c9bf40c45 ("net: phylink: require supported_interfaces to
be filled")
Marvell 88e6320/21 switches fail to be probed:
..
mv88e6085 30be0000.ethernet-1:00: phylink: error: empty supported_interfaces
error creating PHYLINK: -22
..
The problem stems from the use of mv88e6185_phylink_get_caps() to get
the device capabilities.
Since there are serdes only ports 0/1 included, create a new dedicated
phylink_get_caps for the 6320 and 6321 to properly support their
set of capabilities.
Fixes: de5c9bf40c45 ("net: phylink: require supported_interfaces to be filled")
Steffen Bätz (2):
net: dsa: mv88e6xxx: add phylink_get_caps for the mv88e6320/21 family
net: dsa: mv88e6xxx: read cmode on mv88e6320/21 serdes only ports
