In case you have some code ready for testing, the multi-clock MR [1]
now has a "clock" option in the refclock directive to specify the
target clock (by default it's the main system clock).

For a direct synchronization of the PHC on eth0 using a SOCK refclock
chronyd can be configured like this:

clock PHC:eth0 main
refclock SOCK /var/run/refclock.sock clock PHC:eth0 poll 0

It seems to be working nicely with ptp4l as a SOCK source (clock_servo
set to refclock_sock). If you remove the first line, it should
synchronize the system clock with the PHC left running free. This
could be an interesting alternative to phc2sys.
