The FIPER3 (fixed interval period pulse generator) is supported on
DPAA2 and ENETC network controller hardware. This patch is to support
it in ptp_qoriq driver.

Output PPS signal on FIPER2 (Fixed Period Interval Pulse) in default
which is more desired by user.

The alarm function hadn't been supported by PTP clock driver.
The recommended solution PHC + phc2sys + nanosleep provides
best performance. So drop the code of alarm in ptp_qoriq driver.

Export extts_clean_up() function so that dpaa2-ptp
driver is able to reuse it.

Passing the struct ptp_clock_info caps by parameter is passing over 130 bytes
of data by value on the stack. Optimize this by passing it by reference instead.
Also shinks the object code size:
Before:
text data bss dec hex filename
12596 2160 64 14820 39e4 drivers/ptp/ptp_qoriq.o
After:
text data bss dec hex filename
12567 2160 64 14791 39c7 drivers/ptp/ptp_qoriq.o

The 1588 timer on eTSEC Ethernet controller uses different
register memory map with DPAA Ethernet controller.
Now the new ENETC Ethernet controller uses same reigster
memory map with DPAA. To support ENETC, let's use register
memory map of DPAA/ENETC in default.

There is QorIQ 1588 timer IP block on the new ENETC Ethernet
controller. However it uses little endian mode which is different
with before. This patch is to add little endian support for the
driver by using "little-endian" dts node property.

Moved QorIQ PTP clock initialization/free into new functions
ptp_qoriq_init()/ptp_qoriq_free(). These functions could also
be reused by ENETC PTP drvier which is a PCI driver for same
1588 timer IP block.

This patch is to make functions of ptp operations global,
so that ENETC PTP driver which is a PCI driver for same
1588 timer IP block could reuse them.

Strings containing "ptp_qoriq" or "qoriq_ptp" which were used for
structure/function names were complained by users. Let's just use
the unique "ptp_qoriq" to make these names more consistent.
This patch is just to unify the names using "ptp_qoriq". It hasn't
changed any functions.

This patch is to add debugfs support for ptp_qoriq. Current debugfs
supports to control fiper1/fiper2 loopback mode. If the loopback mode
is enabled, the fiper1/fiper2 pulse is looped back into trigger1/
trigger2 input. This is very useful for validating hardware and driver
without external hardware. Below is an example to enable fiper1 loopback.
echo 1 > /sys/kernel/debug/2d10e00.ptp_clock/fiper1-loopback

The external trigger stamp FIFO was introduced as a new feature
for QorIQ 1588 timer IP block. This patch is to support it by
adding a new dts property "fsl,extts-fifo". Any QorIQ 1588 timer
supporting this feature is required to add this property in its
dts node.
In addition, the FIFO should be cleaned up before enabling external
trigger interrupts. Otherwise, there will be interrupts immediately
just after enabling external trigger interrupts.

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.

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.
