2016-01-29ptp: ixp46x: use helpers for converting ns to timespecKefeng Wang1-5/+2
Convert the driver to use ns_to_timespec64() and timespec64_to_ns() instead of open coding the same logic. Signed-off-by: Kefeng Wang <wangkefeng.wang@huawei.com> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-31ptp: ixp46x: convert to the 64 bit get/set time methods.Richard Cochran1-4/+4
The device has a 64 bit clock register, where each clock tick is 16 nanoseconds, and so with this patch the driver is ready for the year 2038. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-03-21ptp: drivers: set the number of programmable pins.Richard Cochran1-0/+1
This patch updates the many PTP Hardware Clock drivers with the newly introduced field that advertises the number of programmable pins. Some of these devices do have programmable pins, but the implementation will have to wait for follow on patches.

2013-09-27ptp: switch to use gpiolibLinus Walleij1-1/+8
This platform supports gpiolib, so remove the custom API use and replace with calls to gpiolib. Also request the GPIO before starting to use it.

2012-09-22ptp: link the phc device to its parent deviceRichard Cochran1-1/+1
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.

2012-04-13ixp4xx_eth: Fix up the get_ts_info ethtool method.Richard Cochran1-2/+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.

This commit brings the author email address macros up to date for four modules in the PTP Hardware Clock subsystem. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-05-24ptp: Added a clock driver for the IXP46x.Richard Cochran1-0/+332
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.
