PTP Hardware Clock devices appear as class devices in sysfs. This patch
changes the registration API to use the parent device, clarifying the
clock's relationship to the underlying device.Signed-off-by: Richard Cochran

If the timex.mode field indicates a query, then we provide the value of
the current frequency adjustment.[ Get rid of extraneous empty lines -DaveM ]

This patch adds a field to the representation of a PTP hardware clock in
order to remember the frequency adjustment value dialed by the user.Adding this field will let us answer queries in the manner of adjtimex
in a follow on patch.Signed-off-by: Richard Cochran

Initial version by Stuart Hodgson
Some PHC device drivers may deliver PPS events with a significant
and variable delay, but still be able to measure precisely what
that delay is.Add a pps_sub_ts() function for subtracting a delay from the
timestamp(s) in a PPS event, and a PTP event type (PTP_CLOCK_PPSUSR)
for which the caller provides a complete PPS event.Signed-off-by: Ben Hutchings

This patch adds an infrastructure for hardware clocks that implement
IEEE 1588, the Precision Time Protocol (PTP). A class driver offers a
registration method to particular hardware clock drivers. Each clock is
presented as a standard POSIX clock.The ancillary clock features are exposed in two different ways, via
the sysfs and by a character device.Signed-off-by: Richard Cochran
