91305f2812 ptp_qoriq: support automatic configuration for ptp timer
This patch is to support automatic configuration for ptp timer.
If required ptp dts properties are not provided, driver could
try to calculate a set of default configurations to initialize
the ptp timer. This makes the driver work for many boards which
don't have the required ptp dts properties in current kernel.
Also the users could set dts properties by themselves according
to their requirement.

a8f62d0c6f ptp: support DPAA FMan 1588 timer in ptp_qoriq
This patch is to support DPAA (Data Path Acceleration Architecture)
1588 timer by adding "fsl,fman-ptp-timer" compatible, sharing
interrupt with FMan, adding FSL_DPAA_ETH dependency, and fixing
up register offset.

f696a21c22 ptp: replace getnstimeofday64() with ktime_get_real_ts64()
getnstimeofday64() is deprecated and getting replaced throughout
the kernel with ktime_get_*() based helpers for a more consistent
interface.

The two functions do the exact same thing, so this is just
a cosmetic change.

ceefc71d4c ptp: rework gianfar_ptp as QorIQ common PTP driver
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.
