| | | | | | | | | | | | | | commit d68fb11c3dae75c8331538dcf083a65e697cc034 upstream. The clock_getres() function must return the resolution in the timespec argument and return 0 for success.

* | ptp: Added a brand new class driver for ptp clocks. | Richard Cochran | 2011-05-23 |
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.
