Alexis Lothoré says: ==================== net: dsa: mv88e6xxx: add 88E6361 support This series brings initial support for Marvell 88E6361 switch. MV88E6361 is a 8 ports switch with 5 integrated Gigabit PHYs and 3 2.5Gigabit SerDes interfaces. It is in fact a new variant in the 88E639X/88E6193X/88E6191X family with a subset of existing features: - port 0: MII, RMII, RGMII, 1000BaseX, 2500BaseX - port 3 to 7: triple speed internal phys - port 9 and 10: 1000BaseX, 25000BaseX Since said family is already well supported in mv88e6xxx driver, adding initial support for this new switch mostly consists in finding the ID exposed in its identification register, adding a proper description in switch description tables in mv88e6xxx driver, and enforcing 88E6361 specificities in mv88e6393x_XXX methods. - first 4 commits introduce an internal phy offset field for switches which have internal phys but not starting from port 0 - 5th commit is a fix on existing switches based on first commits - 6th commit is a slight modification to prepare 886361 support - last commit introduces 88E6361 support in 88E6393X family This initial support has been tested with two samples of a custom board with the following hardware configuration: - a main CPU connected to MV88E6361 using port 0 as CPU port - port 9 wired to a SFP cage - port 10 wired to a G.Hn transceiver The following setup was used: PC <-ethernet-> (copper SFP) - Board 1 - (G.hn) <-phone line(RJ11)-> (G.hn) Board 2 The unit 1 has been configured to bridge SFP port and G.hn port together, which allowed to successfully ping Board 2 from PC. ==================== Link: https://lore.kernel.org/r/20230529080246.82953-1-alexis.lothore@bootlin.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
