[PATCH v1 0/8] Hirschmann Hellcreek DSA driver

[Kurt Kanzenbach <kurt@linutronix.de>]

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 RFC version can be found here:

 https://lkml.kernel.org/netdev/20200618064029.32168-1-kurt@linutronix.de/

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

And two problems I found myself:

 * Fix reg property in DT
 * Fix wrong comments

Please note, that this series depends on

 https://lkml.kernel.org/netdev/20200710090618.28945-2-kurt@linutronix.de/

Tested on top of 5.8.0-rc2.

Thanks,
Kurt
