ptp: update adjfreq callback description

2012-11-26T20:14:07+00:00

commit 87f4d7c1d36f44b0822053b7e5dedc31fdd0ab99 upstream. This patch updates the adjfreq callback description to include a note that the delta in ppb is always relative to the base frequency, and not to the current frequency of the hardware clock.

ptp: Added a brand new class driver for ptp clocks.

2011-05-23T20:01:00+00:00

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.
