This patch adds DT binding document for zynqmp modepin GPIO controller. Modepin GPIO controller has four GPIO pins which can be configurable as input or output. Modepin driver is a bridge between the peripheral driver and GPIO pins. It has set and get APIs for accessing GPIO pins, based on the device-tree entry of reset-gpio property in the peripheral driver, every pin can be configured as input/output and trigger GPIO pin.

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.
