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> Signed-off-by: Shalom Toledo <shalomt@mellanox.com> Reviewed-by: Petr Machata <petrm@mellanox.com> Acked-by: Richard Cochran <richardcochran@gmail.com> Tested-by: Vladimir Oltean <olteanv@gmail.com> Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
