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.
