ptp: remove 32 bit get/set methods.

2015-03-31T16:01:19Z

All of the PHC drivers have been converted to the new methods. This patch converts the three remaining callers within the core code and removes the older methods for good. As a result, the core PHC code is ready for the year 2038. However, some of the PHC drivers are not quite ready yet. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

ptp: introduce get/set time methods with explicit 64 bit seconds.

2015-03-31T16:01:16Z

Converting the PHC drivers over to the new methods is one step along the way to making them ready for 2038. Once all the drivers are up to date, then the old methods will be removed. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

ptp: introduce programmable pins.

2014-03-21T18:21:13Z

This patch adds a pair of new ioctls to the PTP Hardware Clock device interface. Using the ioctls, user space programs can query each pin to find out its current function and also reprogram a different function if desired. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

ptp: update adjfreq callback description

2012-11-03T19:27:07Z

This patch updates the adjfreq callback description to include a note that the delta in ppb is always relative to the base frequency, and not to the current frequency of the hardware clock.

ptp: clarify the clock_name sysfs attribute

2012-09-22T19:42:46Z

There has been some confusion among PHC driver authors about the intended purpose of the clock_name attribute. This patch expands the documation in order to clarify how the clock_name field should be understood. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

ptp: link the phc device to its parent device

2012-09-22T19:42:38Z

PTP Hardware Clock devices appear as class devices in sysfs. This patch changes the registration API to use the parent device, clarifying the clock's relationship to the underlying device. Signed-off-by: Richard Cochran Acked-by: Ben Hutchings Acked-by: Jeff Kirsher Signed-off-by: David S. Miller

pps/ptp: Allow PHC devices to adjust PPS events for known delay

2012-09-07T20:13:28Z

Initial version by Stuart Hodgson Some PHC device drivers may deliver PPS events with a significant and variable delay, but still be able to measure precisely what that delay is. Add a pps_sub_ts() function for subtracting a delay from the timestamp(s) in a PPS event, and a PTP event type (PTP_CLOCK_PPSUSR) for which the caller provides a complete PPS event.

ptp: Add a method for obtaining the device index.

2012-04-04T09:28:45Z

This commit adds a method that MAC drivers may call in order to find out the device number of their associated PTP Hardware Clock. Signed-off-by: Richard Cochran Signed-off-by: David S. Miller

ptp: Added a brand new class driver for ptp clocks.

2011-05-23T20:01:00Z

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.
