ptp: Fix some locking bugs in ptp_read()

2011-06-02T02:29:10Z

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 Acked-by: Richard Cochran Signed-off-by: John Stultz

ptp: Return -EFAULT on copy_to_user() errors

2011-06-02T02:29:08Z

copy_to_user() returns the number of bytes remaining, but we want a negative error code in ptp_ioctl. Signed-off-by: Dan Carpenter Acked-by: Richard Cochran Signed-off-by: John Stultz

ptp: Added a clock driver for the National Semiconductor PHYTER.

2011-05-23T20:10:23Z

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 Signed-off-by: John Stultz

ptp: Added a clock driver for the IXP46x.

2011-05-23T20:10:19Z

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.

2011-05-23T20:10:14Z

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. Signed-off-by: Richard Cochran Acked-by: David S. Miller Acked-by: John Stultz Signed-off-by: John Stultz

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.
