Subject: [PATCH v2 0/8] Hirschmann Hellcreek DSA driver
Date: Thu, 23 Jul 2020 10:17:06 +0200
Message-ID: <20200723081714.16005-1-kurt@linutronix.de> (raw)

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@linutronix.de/
 * https://lkml.kernel.org/netdev/20200710113611.3398-1-kurt@linutronix.de/

This series depends on:

 * https://lkml.kernel.org/netdev/20200723074946.14253-1-kurt@linutronix.de/

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.
