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 and
hardware timestamping.

This work is part of the AccessTSN project: https://www.accesstsn.com/

Due to the changes with the compatible strings and platform data patch 2 and 7
should be re-reviewed.

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
