selftests: ptp: Add Physical Hardware Clock test
Test the PTP Physical Hardware Clock functionality using the "phc_ctl" (a
part of "linuxptp").
The test contains three sub-tests:
* "settime" test
* "adjtime" test
* "adjfreq" test
"settime" test:
* set the PHC time to 0 seconds.
* wait for 120.5 seconds.
* check if PHC time equal to 120.XX seconds.
"adjtime" test:
* set the PHC time to 0 seconds.
* adjust the time by 10 seconds.
* check if PHC time equal to 10.XX seconds.
"adjfreq" test:
* adjust the PHC frequency to be 1% faster.
* set the PHC time to 0 seconds.
* wait for 100.5 seconds.
* check if PHC time equal to 101.XX seconds.
Usage:
$ ./phc.sh /dev/ptp<X>
It is possible to run a subset of the tests, for example:
* To run only the "settime" test:
$ TESTS="settime" ./phc.sh /dev/ptp<X>
