This driver adds support for the Renesas Window Watchdog Timer (WWDT). Because it can only be setup once after boot and we cannot know if this already happened in early boot stages, it is mandated that the firmware configures the watchdog. Linux then adapts according to the given setup. Note that this watchdog only reports an overflow to the Error Control Module (ECM) and does not reset the SoC on its own.

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.
