Russell King says: ==================== net: dsa: mv88e6xxx: convert to phylink_generic_validate() The overall objective of this series is to convert the mv88e6xxx DSA driver to use phylink_generic_validate(). Patch 1 adds a new helper mv88e6352_g2_scratch_port_has_serdes() which indicates whether an 88e6352 port has a serdes associated with it. This is necessary as ports 4 and 5 will normally be in automedia mode, where the CMODE field in the port status register will change e.g. between 15 (internal PHY) and 9 (1000base-X) depending on whether the serdes has link. The existing code caches the cmode field, and depending whether the serdes has link at probe time, determines whether we allow things such as the serdes statistics to be accessed. This means if the link isn't up at probe time, the serdes is essentially unavailable. Patch 1 addresses this by reading the pin configuration to find out whether the serdes is attached to port 4 or port 5. Patch 2 is a joint effort between myself and Marek Behún, adding the supported interfaces and MAC capabilities to all mv88e6xxx supported switch devices. This is slightly more restrictive than the original code as we didn't used to care too much about the interface mode, but with this we do - which is why we must know if there's a serdes associated now. Patch 3 switches mv88e6xxx to use the generic validation by removing the initialisation of the phylink_validate pointer in the dsa_ops struct. Patch 4 updates the statistics code to use the new helper in patch 1, so the serdes statistics are available even if the link was down at driver probe time. ==================== Signed-off-by: David S.

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.
