Kurt Kanzenbach says: ==================== Hirschmann Hellcreek DSA driver this series adds a DSA driver for the Hirschmann Hellcreek TSN switch IP. Characteristics of that IP: * Full duplex Ethernet interface at 100/1000 Mbps on three ports * IEEE 802.1Q-compliant Ethernet Switch * IEEE 802.1Qbv Time-Aware scheduling support * IEEE 1588 and IEEE 802.1AS support That IP is used e.g. in https://www.arrow.com/en/campaigns/arrow-kairos Due to the hardware setup the switch driver is implemented using DSA. A special tagging protocol is leveraged. Furthermore, this driver supports PTP and hardware timestamping. This work is part of the AccessTSN project: https://www.accesstsn.com/ The previous versions can be found here: * https://lkml.kernel.org/netdev/20200618064029.32168-1-kurt@linutronix.de/ * https://lkml.kernel.org/netdev/20200710113611.3398-1-kurt@linutronix.de/ * https://lkml.kernel.org/netdev/20200723081714.16005-1-kurt@linutronix.de/ * https://lkml.kernel.org/netdev/20200820081118.10105-1-kurt@linutronix.de/ * https://lkml.kernel.org/netdev/20200901125014.17801-1-kurt@linutronix.de/ * https://lkml.kernel.org/netdev/20200904062739.3540-1-kurt@linutronix.de/ * https://lkml.kernel.org/netdev/20201004112911.25085-1-kurt@linutronix.de/ * https://lkml.kernel.org/netdev/20201028074221.29326-1-kurt@linutronix.de/ Changes since v7: * Simplify tagging code (rebase to net-next) * Pass info instead of ptr (Florian Fainelli) * Fix yamllint warnings (Rob Herring) Changes since v6: * Add .tail_tag = true (Vladimir Oltean) * Fix vlan_filtering=0 bridges (Vladimir Oltean) * Enforce restrictions (Vladimir Oltean) * Sort stuff alphabetically (Vladimir Oltean) * Rename hellcreek.yaml to hirschmann,hellcreek.yaml * Typo fixes Changes since v5: * Implement configure_vlan_while_not_filtering behavior (Vladimir Oltean) * Minor cleanups Changes since v4: * Fix W=1 compiler warnings (kernel test robot) * Add tags Changes since v3: * Drop TAPRIO support (David Miller) => Switch to mutexes due to the lack of hrtimers * Use more specific compatible strings and add platform data (Andrew Lunn) * Fix Kconfig ordering (Andrew Lunn) Changes since v2: * Make it compile by getting all requirements merged first (Jakub Kicinski, David Miller) * Use "tsn" for TSN register set (Rob Herring) * Fix DT binding issues (Rob Herring) Changes since v1: * Code simplifications (Florian Fainelli, Vladimir Oltean) * Fix issues with hellcreek.yaml bindings (Florian Fainelli) * Clear reserved field in ptp v2 event messages (Richard Cochran) * Make use of generic ptp parsing function (Richard Cochran, Vladimir Oltean) * Fix Kconfig (Florian Fainelli) * Add tags (Florian Fainelli, Rob Herring, Richard Cochran) Changes since RFC ordered by reviewers: * Andrew Lunn * Use dev_dbg for debug messages * Get rid of __ function names where possible * Use reverse xmas tree variable ordering * Remove redundant/useless checks * Improve comments e.g. for PTP * Fix Kconfig ordering * Make LED handling more generic and provide info via DT * Setup advertisement of PHYs according to hardware * Drop debugfs patch * Jakub Kicinski * Fix compiler warnings * Florian Fainelli * Switch to YAML DT bindings * Richard Cochran * Fix typo * Add missing NULL checks ==================== Link: https://lore.kernel.org/r/20201103071101.3222-1-kurt@linutronix.de 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.
