* ptp: Added a clock driver for the National Semiconductor PHYTER.Richard Cochran2011-05-231-0/+19
| | | | | | | | | This patch adds support for the PTP clock found on the DP83640. The basic clock operations and one external time stamp have been implemented. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: John Stultz <john.stultz@linaro.org>
* ptp: Added a clock driver for the IXP46x.Richard Cochran2011-05-233-0/+346
| | | | | | | | | | | | This patch adds a driver for the hardware time stamping unit found on the IXP465. The basic clock operations and an external trigger are implemented.

* ptp: Added a clock that uses the eTSEC found on the MPC85xx.Richard Cochran2011-05-231-0/+13
| | | | | | | | | | | The eTSEC includes a PTP clock with quite a few features. This patch adds support for the basic clock adjustment functions, plus two external time stamps, one alarm, and the PPS callback.

* ptp: Added a brand new class driver for ptp clocks.Richard Cochran2011-05-236-0/+860
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.
