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

[Yangbo Lu <yangbo.lu@nxp.com>]

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.

Yangbo Lu (5):
  ptp_qoriq: fix interrupt enabling and handling
  ptp_qoriq: support external trigger stamp FIFO
  dt-binding: ptp_qoriq: document "fsl,extts-fifo" property
  ARM: dts: ls1021a: add 1588 external trigger stamp fifo support
  ptp_qoriq: add fiper pulse loopback support
