Parthiban Veerasooran says: ==================== net: phy: Add Open Alliance TC14 10Base-T1S PHY cable diagnostic support This patch series adds Open Alliance TC14 (OATC14) 10BASE-T1S cable diagnostic feature support to the Linux kernel PHY subsystem and enable this feature for Microchip LAN867x Rev.D0 PHYs. These patches provide standardized cable test functionality for 10BASE-T1S Ethernet PHYs, allowing users to perform cable diagnostics via ethtool. Patch Summary: 1. add OATC14 10BASE-T1S PHY cable diagnostic support - Implements support for the OATC14 cable diagnostic feature in Clause 45 PHYs. - Adds functions to start a cable test and retrieve its status, mapping hardware results to ethtool codes. - Exports these functions for use by PHY drivers. - Open Alliance TC14 10BASE-T1S Advanced Diagnostic PHY Features. https://opensig.org/wp-content/uploads/2025/06/OPEN_Alliance_10BASE-T1S_Advanced_PHY_features_for-automotive_Ethernet_V2.1b.pdf 2. add cable diagnostic support for LAN867x Rev.D0 - Integrates the generic OATC14 cable test functions into the Microchip LAN867x Rev.D0 PHY driver. - Enables ethtool cable diagnostics for this PHY, improving troubleshooting and maintenance. ==================== Link: https://patch.msgid.link/20251105051213.50443-1-parthiban.veerasooran@microchip.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 reStructuredText 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.
