Enables advertisement of the maximum offset supported by the phase control functionality of PHCs. The callback is used to return an error if an offset not supported by the PHC is used in ADJ_OFFSET. The ioctls PTP_CLOCK_GETCAPS and PTP_CLOCK_GETCAPS2 now advertise the maximum offset a PHC's phase control functionality is capable of supporting. Introduce new sysfs node, max_phase_adjustment.

selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET
Previously, timestamps were printed using "%lld.%u" which is incorrect for nanosecond values lower than 100,000,000 as they're fractional digits, therefore leading zeros are meaningful.
This patch changes the format strings to "%lld.%09u" in order to add leading zeros to the nanosecond value.

testptp: add new options for perout phase and pulse width
Extend the example program for PTP ancillary functionality with the ability to configure not only the periodic output's period (frequency), but also the phase and duty cycle (pulse width) which were newly introduced.
The ioctl level also needs to be updated to the new PTP_PEROUT_REQUEST2, since the original PTP_PEROUT_REQUEST doesn't support this functionality. For an in-tree testing program, not having explicit backwards compatibility is fine, as it should always be tested with the current kernel headers and sources.
Tested with an oscilloscope on the felix switch PHC:
echo '2 0' > /sys/class/ptp/ptp1/pins/switch_1588_dat0 ./testptp -d /dev/ptp1 -p 1000000000 -w 100000000 -H 1000 -i 0

posix-timers: Prevent UB from shifting negative signed value
Shifting a negative signed number is undefined behavior. Looking at the macros MAKE_PROCESS_CPUCLOCK and FD_TO_CLOCKID, it seems that the subexpression:
(~(clockid_t) (pid) << 3)
where clockid_t resolves to a signed int, which once negated, is undefined behavior to shift the value of if the results thus far are negative.
It was further suggested to make these macros into inline functions.

testptp: add new options for perout phase and pulse width Extend the example program for PTP ancillary functionality with the ability to configure not only the periodic output's period (frequency), but also the phase and duty cycle (pulse width) which were newly introduced. The ioctl level also needs to be updated to the new PTP_PEROUT_REQUEST2, since the original PTP_PEROUT_REQUEST doesn't support this functionality. For an in-tree testing program, not having explicit backwards compatibility is fine, as it should always be tested with the current kernel headers and sources. Tested with an oscilloscope on the felix switch PHC: echo '2 0' > /sys/class/ptp/ptp1/pins/switch_1588_dat0 ./testptp -d /dev/ptp1 -p 1000000000 -w 100000000 -H 1000 -i 0 Signed-off-by: Vladimir Oltean <olteanv@gmail.com> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

Ever since commit 3a06c7ac24f9 ("posix-clocks: Remove interval timer facility and mmap/fasync callbacks") the possibility of PHC based posix timers has been removed.
