Hi, 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, hardware timestamping and TAPRIO offloading. 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@xxxxxxxxxxxxx/ * https://lkml.kernel.org/netdev/20200710113611.3398-1-kurt@xxxxxxxxxxxxx/ This series depends on: * https://lkml.kernel.org/netdev/20200723074946.14253-1-kurt@xxxxxxxxxxxxx/ 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) I didn't change the bridge/tagging setup, as I didn't find a better way to do it.
