It's not on the list (probably due to not being ptp-ready "out of the box" under Linux) but Microsemi's VSC8572 (nee Vitesse) and family could do the job (for 2-step PTP). https://www.microsemi.com/product-directory/gigabit-ethernet-phys/3905-vsc8572
For various reasons we ended up not using this feature so unfortunately I can't comment on the effort required to make it happen. Whilst there seems to be a Linux phylib driver for the part, last I checked timestamping wasn't implemented so there could be some fair bringup work. YMMV, but the part exists and hopefully is a useful datapoint in your search. - David On Mon, 21 Jan 2019 at 20:08, Arthur Dent <arthurd...@cyberdude.com> wrote: > Hi > On my Cyclone V SoC board I have ptp running with HW timestamping in MAC > (stmmac), but I need even better accuracy, i.e. hardware timestamping in > PHY.
