Subject: [RFC Patch net-next 0/6] net: dsa: microchip: add gPTP support for LAN937x switch

The LAN937x switch has capable for supporting IEEE 1588 PTP protocol. This
patch series add gPTP profile 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. But the testing is
done only for lan937x switch.

Arun Ramadoss (6):
  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
