Bogdan Purcareata says: ==================== net: phy: Support managed Cortina phys So far, the Cortina family phys (CS4340 in this particular case) are only supported in fixed link mode (via fixed_phy_register). The generic 10G phy driver does not work well with the phylib state machine, when the phy is registered via of_phy_connect. This prohibits the user from describing the phy nodes in the device tree. In order to support this scenario, and to properly describe the board device tree, add a minimal Cortina driver that reads the status from the right register. With the generic 10G C45 driver, the kernel will print messages like: [ 0.226521] mdio_bus 8b96000: Error while reading PHY16 reg at 1.6 [ 0.232780] mdio_bus 8b96000: Error while reading PHY16 reg at 1.5 v3 -> v4: - Add trademark info. - Minor documentation entry consistency nit. v2 -> v3: - Add documentation entry. v1 -> v2: - Change approach for getting the phy_id from hacking get_phy_c45_ids to describing the device in the device tree via ethernet-phy-id. More patch version changes per individual patches. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
