Subject[Patch net-next v1 00/12] net: dsa: microchip: add PTP support for KSZ9563/KSZ8563 and LAN937x
Date
KSZ9563/KSZ8563 and  LAN937x switch are capable for supporting IEEE 1588 PTP
protocol. LAN937x has the same PTP register set similar to KSZ9563, hence the
implementation has been made common for the KSZ switches. KSZ9563 does not
support two step timestamping but LAN937x supports both. Tested the 1step &
2step p2p timestamping in LAN937x and p2p1step timestamping in KSZ9563.

This patch series is based on the Christian Eggers PTP support for KSZ9563.
Applied the Christian patch and updated as per the latest refactoring of KSZ
series code. The features added on top are PTP packet Interrupt
implementation based on nested handler, LAN937x two step timestamping and
programmable per_out pins.

RFC v2 -> Patch v1
- Changed the patch author based on past patch submission
- Changed the commit message prefix as net: dsa: microchip: ptp
Individual patch changes are listed in correspondig commits.

RFC v1 -> v2
- Added the p2p1step timestamping and conditional execution of 2 step for
LAN937x only.
- Added the periodic output support
