Geert Uytterhoeven 2a9a2f27d3 gpio: pca953x: Add wake-up support
Implement the irq_set_wake() method in the (optional) irq_chip of the
GPIO expander, and propagate wake-up settings to the upstream interrupt
controller.  This allows GPIOs connected to a PCA953X GPIO expander to
serve as wake-up sources.

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.
