[PATCH v2 3/4] Add support for driver cross-timestamp to PTP_SYS_OFFSET ioctl

2015-08-07 Thread Christopher Hall
This patch allows system and device time ("cross-timestamp") to be performed by the driver. Currently, the cross-timestamping is performed in the PTP_SYS_OFFSET ioctl. The PTP clock driver reads gettimeofday() and the gettime64() callback provided by the driver. The cross-timestamp is best effort
