![]() In ("ptp: ocp: Have FPGA fold in ns adjustment for adjtime."), the
ns adjustment was written to the FPGA register, so the clock could
accurately perform adjustments.
However, the adjtime() call passes in a s64, while the clock adjustment
registers use a s32. When trying to perform adjustments with a large
value (37 sec), things fail.
Examine the incoming delta, and if larger than 1 sec, use the original
(coarse) adjustment method. If smaller than 1 sec, then allow the
FPGA to fold in the changes over a 1 second window.
Fixes:
