Andy Shevchenko fdc1f5dfb9 gpio: sch: Hook into ACPI GPE handler to catch GPIO edge events
Neither the ACPI description on Intel Minnowboard (v1) platform provides
the required information to establish a generic handling nor the hardware
capable of doing it. According to the data sheet the hardware can generate
SCI events. Therefore, we need to hook from the driver into GPE handler of
the ACPI subsystem in order to catch and report GPIO-related events.

Validated on the Inlel Minnowboard (v1) platform and Intel Galileo Gen 2.

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.
