net: dsa: Add DSA driver for Hirschmann Hellcreek switches Add a basic DSA driver for Hirschmann Hellcreek switches. Those switches are implementing features needed for Time Sensitive Networking (TSN) such as support for the Time Precision Protocol and various shapers like the Time Aware Shaper. This driver includes basic support for networking: * VLAN handling * FDB handling * Port statistics * STP * Phylink Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de> Reviewed-by: Vladimir Oltean <olteanv@gmail.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org> 2020-11-03 08:10:56 +01:00			`# SPDX-License-Identifier: GPL-2.0`

net: dsa: hellcreek: Add PTP clock support The switch has internal PTP hardware clocks. Add support for it. There are three clocks: * Synchronized * Syntonized * Free running Currently the synchronized clock is exported to user space which is a good default for the beginning. The free running clock might be exported later e.g. for implementing 802.1AS-2011/2020 Time Aware Bridges (TAB). The switch also supports cross time stamping for that purpose. The implementation adds support setting/getting the time as well as offset and frequency adjustments. However, the clock only holds a partial timeofday timestamp. This is why we track the seconds completely in software (see overflow work and last_ts). Furthermore, add the PTP multicast addresses into the FDB to forward that packages only to the CPU port where they are processed by a PTP program.
