Claudiu Beznea b2bd65fbb6 pinctrl: renesas: rzg2l: Add suspend/resume support for pull up/down
The Renesas RZ/G3S supports a power-saving mode where power to most of
the SoC components is lost, including the PIN controller.  Save and
restore the pull-up/pull-down register contents to ensure the
functionality is preserved after a suspend/resume cycle.

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.
