* ptp: add the pin GET/SETFUNC ioctls to the testptp program.Richard Cochran2014-03-211-3/+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>
* ptp: Allow selecting trigger/event index in testptpStefan Sørensen2014-02-041-3/+8
| | | | | | | | | | Currently the trigger/event is hardcoded to 0, this patch adds a new command line argument -i to select an arbitrary trigger/ event.

* ptp: add the PTP_SYS_OFFSET ioctl to the testptp programDong Zhu2013-09-231-2/+63
| | | | | | | | This patch add a method into testptp.c to measure the time offset between phc and system clock through the ioctl PTP_SYS_OFFSET. Signed-off-by: Dong Zhu <bluezhudong@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ptp: Added a brand new class driver for ptp clocks.Richard Cochran2011-05-233-0/+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.
