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.
