Add suspend/resume hooks in pinctrl driver to handle S2RAM operations. Beyond the traditional register save/restore operations, these hooks also keep the GPIOs used for both-edge IRQ synchronized between their level (low/high) and expected IRQ polarity (falling/rising edge). Since pinctrl is an infrastructure module, its resume should be issued prior to other IO drivers. The pinctrl PM operations are requested at early/late stages for this reason.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
