Patchset overview: Patch #1 returns correct ptp timestamp in nanoseconds captured when external timestamp event occurs. Patch #2 adds 1-step mode support. Patch #3 implements software workaround to generate PPS output properly. Patch #4 provides a software workaround for the rollover register default value, which causes ptp to return the wrong timestamp. v2 changes: no code changes, added PTP maintainer to CC list.
