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/ 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 Kamil Alkhouri (2): net: dsa: hellcreek: Add PTP clock support net: dsa: hellcreek: Add support for hardware timestamping Kurt Kanzenbach (5): net: dsa: Add tag handling for Hirschmann Hellcreek switches net: dsa: Add DSA driver for Hirschmann Hellcreek switches net: dsa: hellcreek: Add PTP status LEDs dt-bindings: Add vendor prefix for Hirschmann dt-bindings: net: dsa: Add documentation for Hellcreek switches Vladimir Oltean (1): net: dsa: Give drivers the chance to veto certain upper devices .../net/dsa/hirschmann,hellcreek.yaml | 127 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + drivers/net/dsa/Kconfig | 2 + drivers/net/dsa/Makefile | 1 + drivers/net/dsa/hirschmann/Kconfig | 9 + drivers/net/dsa/hirschmann/Makefile | 5 + drivers/net/dsa/hirschmann/hellcreek.c | 1339 +++++++++++++++++ drivers/net/dsa/hirschmann/hellcreek.h | 286 ++++ .../net/dsa/hirschmann/hellcreek_hwtstamp.c | 479 ++++++ .../net/dsa/hirschmann/hellcreek_hwtstamp.h | 58 + drivers/net/dsa/hirschmann/hellcreek_ptp.c | 452 ++++++ drivers/net/dsa/hirschmann/hellcreek_ptp.h | 76 + .../platform_data/hirschmann-hellcreek.h | 23 + include/net/dsa.h | 8 + net/dsa/Kconfig | 6 + net/dsa/Makefile | 1 + net/dsa/slave.c | 12 + net/dsa/tag_hellcreek.c | 102 ++ 18 files changed, 2988 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/dsa/hirschmann,hellcreek.yaml create mode 100644 drivers/net/dsa/hirschmann/Kconfig create mode 100644 drivers/net/dsa/hirschmann/Makefile create mode 100644 drivers/net/dsa/hirschmann/hellcreek.c create mode 100644 drivers/net/dsa/hirschmann/hellcreek.h create mode 100644 drivers/net/dsa/hirschmann/hellcreek_hwtstamp.c create mode 100644 drivers/net/dsa/hirschmann/hellcreek_hwtstamp.h create mode 100644 drivers/net/dsa/hirschmann/hellcreek_ptp.c create mode 100644 drivers/net/dsa/hirschmann/hellcreek_ptp.h create mode 100644 include/linux/platform_data/hirschmann-hellcreek.h create mode 100644 net/dsa/tag_hellcreek.c Reviewed-by: Florian Fainelli
