====================
External trigger stamp fifo support for ptp_qoriq
This patch-set is to add external trigger stamp fifo support by a new
binding "fsl,extts-fifo", and to add fiper pulse loopback support which
is very useful for validating trigger without external hardware.
Also fixed issues in interrupt enabling/handling.
"fsl,extts-fifo" is required to be added into 1588 timer dts node whose
hardware supports it. The work will be done for some QorIQ platforms dts in
the near future.
