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
