Miroslav Lichvar 4e24248a71 Add options to not apply leap seconds in kernel.
Add kernel_leap option for ptp4l and -x option for phc2sys to disable
setting of the STA_INS/STA_DEL bit to slowly correct the one-second
offset by servo.

Miroslav Lichvar eb93926bc9 phc2sys: Handle leap seconds.
Update the currentUtcOffset and leap61/59 values at one minute
interval. When a leap second is detected, set the STA_INS/STA_DEL
bit for the system clock.

Modify the pmc to allow non-blocking operation. Run it on each clock

Miroslav Lichvar 3136e3e46c Add summary statistics.
Add new options to ptp4l and phc2sys to print summary statistics of the
clock instead of the individual samples.

[ RC - Fix () function prototype with (void).
     - Use unsigned for sample counter.
     - Fix over-zealous line breaks. ]

Miroslav Lichvar cb5ebd9b24 Change label of frequency offset.
Change the label of the frequency offset in the clock messages printed
by ptp4l and phc2sys from "adj" to "freq" to indicate it's a frequency
value.

Also, modify clock_no_adjust() to print the frequency offset instead of
the ratio and use PRId64 instead of lld to print int64_t values.

Richard Cochran f530ae9333 Hide the grandmaster port state.
There really is no such state, but there probably should have been one.
In any case, we do have one just to make the code simpler, but this should
not appear in the management responses. This patch fixes the issue by
covering over our tracks before sending a response.

Miroslav Lichvar 74692bb1b0 phc2sys: include PTP management client.
Add a new option to wait for ptp4l to be in a synchronized state.
Periodically check PORT_DATA_SET and wait until there is a port in
SLAVE, MASTER or GRAND_MASTER state. Also, set the default
synchronization offset according to the currentUtcOffset value from
TIME_PROPERTIES_DATA_SET and the direction of the clock synchronization.

Miroslav Lichvar c5ce4ef764 phc2sys: read PHC with each PPS sample.
In the PPS loop, instead of setting the system clock from the PHC only
once on start, read PHC with each PPS sample and use the time stamp to
get the whole number of seconds in the offset. This will prevent phc2sys
from losing track of the system clock.

Also, check if the PPS is synchronized to the PHC.

Miroslav Lichvar fc1a695493 phc2sys: don't zero clock frequency on start.
Instead of always starting at zero frequency offset, read the currently
stored value on start and pass it to the servo. As the read may silently
fail and return zero, set the clock frequency back to the read value to
make sure it's always equal to the actual frequency of the clock.

Jacob Keller 004b62d22b sk: change sk_interface_phc to sk_get_ts_info
this patch changes sk_interface_phc to sk_get_ts_info, by allowing the function
to store all the data returned by Ethtool's get_ts_info IOCTL in a struct. A new
struct "sk_ts_info" contains the same data as well as a field for specifying the
structure as valid (in order to support old kernels without the IOCTL). The
valid field should be set only when the IOCTL successfully populates the fields.

A follow-on patch will add new functionality possible because of these
changes. This patch only updates the programs which use the call to perform the
minimum they already do, using the new interface.

Miroslav Lichvar 2fcf5cbb4f Add non-PPS mode to phc2sys.
As some PHC hardware/drivers don't provide PPS, it may be useful to keep the
system clock synchronized to PHC via clock_gettime(). While the precision
of the clock is only in microsecond range, the error seems to be quite stable.

The -d parameter now can be omitted if -s is provided.
