[v2,0/5] External trigger stamp fifo support for ptp_qoriq

Message

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 uses it. The work will be done for some QorIQ platforms dts in
the near future.

  ptp_qoriq: fix interrupt enabling and handling
