phc2sys: read PHC with each PPS sample.
...
In the PPS loop, instead of setting the system clock from the PHC only
once on start, read PHC with each PPS sample and use the time stamp to
get the whole number of seconds in the offset. This will prevent phc2sys
from losing track of the system clock.
Also, check if the PPS is synchronized to the PHC.

phc2sys: remove unnecessary clock step with non-PPS loops.
...
With non-PPS loops let the servo make the inital correction. Move the
code to the PPS loop and change it to use the sample filtering to reduce
the error in the initial correction.

phc2sys: don't zero clock frequency on start.
...
Instead of always starting at zero frequency offset, read the currently
stored value on start and pass it to the servo. As the read may silently
fail and return zero, set the clock frequency back to the read value to
make sure it's always equal to the actual frequency of the clock.

Modify PI servo to set frequency when jumping.
...
Similarly to the servo in phc2sys, when clock is stepped, set
immediately also its frequency. This significantly improves the initial
convergence with large frequency offsets.
