[ Upstream commit b3f1a164c7f742503dc7159011f7ad6b092b660e ]
As of commit de5c9bf40c45 ("net: phylink: require supported_interfaces to
be filled") Marvell 88e6350 switches fail to be probed:
...
mv88e6085 d0072004.mdio-mii:11: switch 0x3710 detected: Marvell 88E6350, revision 2
mv88e6085 d0072004.mdio-mii:11: phylink: error: empty supported_interfaces
error creating PHYLINK: -22
mv88e6085: probe of d0072004.mdio-mii:11 failed with error -22
...
The problem stems from the use of mv88e6185_phylink_get_caps() to get
the device capabilities. Create a new dedicated phylink_get_caps for the
6351 family (which the 6350 is one of) to properly support their set of
capabilities.
According to chip.h the 6351 switch family includes the 6171, 6175, 6350
and 6351 switches, so update each of these to use the correct
phylink_get_caps.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
