Andy Shevchenko 76ad884be0 pinctrl: intel: Save and restore pins in "direct IRQ" mode
commit 6989ea4881 upstream.

The firmware on some systems may configure GPIO pins to be
an interrupt source in so called "direct IRQ" mode. In such
cases the GPIO controller driver has no idea if those pins
are being used or not. At the same time, there is a known bug
in the firmwares that don't restore the pin settings correctly
after suspend, i.e. by an unknown reason the Rx value becomes
inverted.

Hence, let's save and restore the pins that are configured
as GPIOs in the input mode with GPIROUTIOXAPIC bit set.

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.
