Adds interrupt support to the Xilinx GPIO driver so that rising and falling edge line events can be supported. Since interrupt support is an optional feature in the Xilinx IP, the driver continues to support devices which have no interrupt provided. Depends on OF_GPIO framework for of_xlate function to translate gpiospec to the GPIO number and flags.

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.
