The page did not match the code in several places. - Describe struct ptp_ops_s as it is: adjfine takes parts per billion, adjphase, getres and control exist, there is no getcaps, and gettime has a system timestamp argument. State which operations are optional and give the real ptp_clock_register() arguments. - Replace the CLOCKFD() macro, which does not exist, with the clock identifier built from CLOCK_SHIFT and CLOCK_FD, in all examples. - Fix the frequency values: struct timex freq is in parts per million with 16 fractional bits, so +10 ppm is 655360. - List the modes clock_adjtime() handles for a PTP clock (ADJ_SETOFFSET, ADJ_FREQUENCY, ADJ_OFFSET for the phase) and say that the others return -ENOTSUP. - PTP_CLOCK_GETTIME and PTP_CLOCK_SETTIME take a struct timespec. Add the ioctls that were missing. - The dummy driver uses CLOCK_REALTIME, not the monotonic clock. - Point to ptpd instead of ptp4l and timemaster, which are not part of NuttX, and use the real CONFIG_DEBUG_PTP options.
