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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
