The overall one-step functionality is described IEEE 1588.

The device is from here:

   https://www.zhaw.ch/en/engineering/institutes-centres/ines/products-and-services/ptp-ieee-1588/ptp-hardware/#c43991

The only other docs that I have is a PDF of the register layout, but I
don't think I can redistribute that.  Actually, there really isn't any
detail in that doc at all.

Thanks,
Richard
