2011-12-06	ptp: Fix clock_getres() implementation	Thomas Gleixner	1	-1/+3
	The clock_getres() function must return the resolution in the timespec argument and return 0 for success. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: John Stultz <john.stultz@linaro.org> Cc: stable@kernel.org Cc: Richard Cochran <richard.cochran@omicron.at>
2011-06-01	ptp: Fix some locking bugs in ptp_read()	Dan Carpenter	1	-4/+4
	In ptp_read there is an unlock missing on an error path, and a double unlock on another error path. Signed-off-by: Dan Carpenter <error27@gmail.com> Acked-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: John Stultz <john.stultz@linaro.org>
2011-06-01	ptp: Return -EFAULT on copy_to_user() errors	Dan Carpenter	1	-1/+2
	copy_to_user() returns the number of bytes remaining, but we want a negative error code in ptp_ioctl. Signed-off-by: Dan Carpenter <error27@gmail.com> Acked-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: John Stultz <john.stultz@linaro.org>
2011-05-23	ptp: Added a clock driver for the National Semiconductor PHYTER.	Richard Cochran	1	-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>
2011-05-23	ptp: Added a clock driver for the IXP46x.	Richard Cochran	3	-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.

2011-05-23	ptp: Added a clock that uses the eTSEC found on the MPC85xx.	Richard Cochran	1	-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.

2011-05-23	ptp: Added a brand new class driver for ptp clocks.	Richard Cochran	6	-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.
