Add support for the GPIO controller found on some QIXIS FPGAs in Layerscape boards such as LX2160ARDB and LS1046AQDS. This driver is using gpio-regmap. A GPIO controller has a maximum of 8 lines (all found in the same register). Even within the same controller, the GPIO lines' direction is fixed, which mean that both input and output lines are found in the same register. This is why the driver also passed to gpio-regmap the newly added .fixed_direction_output bitmap to represent the true direction of the lines.

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 reStructuredText 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.
