The driver is definitely doing something funky as evidenced above, and unless the driver is available we can't really comment. I suggest using the provided testptp tool provided in the Linux Kernel documentation to do some sanity checks on all your ptp code paths for adjtime, settime, gettime, adjfreq, etc. Verify these are doing what you expect before you continue your debugging with ptp4l.
