2014-03-21ptp: add the pin GET/SETFUNC ioctls to the testptp program.Richard Cochran1-3/+55
This patch adds a option to the test program that lists the programmable pins on a PTP Hardware Clock device, assuming there are any such pins. A second option lets the user reprogram the auxiliary function of a single pin. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-05-24ptp: Added a brand new class driver for ptp clocks.Richard Cochran3-0/+503
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.
