gianfar_ptp was the PTP clock driver for 1588 timer module of Freescale QorIQ eTSEC (Enhanced Three-Speed Ethernet Controllers) platforms. Actually QorIQ DPAA (Data Path Acceleration Architecture) platforms is also using the same 1588 timer module in hardware. This patch is to rework gianfar_ptp as QorIQ common PTP driver to support both DPAA and eTSEC. Moved gianfar_ptp.c to drivers/ptp/, renamed it as ptp_qoriq.c, and renamed many variables. There were not any function changes. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The IEEE 1588 standard defines a method to precisely
|
|
synchronize distributed clocks over Ethernet networks. The
|
|
standard defines a Precision Time Protocol (PTP), which can
|
|
be used to achieve synchronization within a few dozen
|
|
microseconds. In addition, with the help of special hardware
|
|
time stamping units, it can be possible to achieve
|
|
synchronization to within a few hundred nanoseconds.

devices. If you want to use a PTP clock, then you should

also enable at least one clock driver as well.
