Subject[RFC Patch net-next v2 0/8] net: dsa: microchip: add PTP support for KSZ9x and LAN937x
Date
The LAN937x switch has capable for supporting IEEE 1588 PTP protocol. This
patch series add PTP support and tested using the ptp4l application.
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.

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

Arun Ramadoss (7):
net: dsa: microchip: adding the posix clock support
net: dsa: microchip: Initial hardware time stamping support
net: dsa: microchip: Manipulating absolute time using ptp hw clock
net: dsa: microchip: enable the ptp interrupt for timestamping
net: dsa: microchip: Adding the ptp packet reception logic
net: dsa: microchip: add the transmission tstamp logic
net: dsa: microchip: ptp: add periodic output signal

Christian Eggers (1):
net: ptp: add helper for one-step P2P clocks
