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
