* | pch_gbe: correct receive time stamp filteringTakahiro Shimizu2012-04-211-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the driver so that multicast PTP event messages can be recognized by the hardware time stamping unit. The station address register must be set according to the desired transport type.

| | | | | | | | | | | | | | | | | | | | | | | | The code in phc_gbe_main will need to call this method in order to set the station address register according to the receive time stamping filter.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the helper functions that give the transmit and receive time stamps to return nanoseconds, instead of arbitrary clock ticks.

* | ixp4xx_eth: Fix up the get_ts_info ethtool method.Richard Cochran2012-04-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | Commit e77bd1ec121ee4163a6b42a44e87b2e382c39e04 added support for a new ethtool function, but that cannot compile due to a misnamed global variable. Not that it really matters (since the IXP4xx does compile either, as of about Linux 3.1) but just in case, this patch fixes the misnamed variable in the PHC driver.

* 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.
