• d94ba80eb   ptp: Added a brand new class driver for ptp clocks. ... Browse Code »

  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.
