Currently when running the samples/watchdog/watchdog-simple.c
application and forcing a kernel crash by doing:
# ./watchdog-simple &
# echo c > /proc/sysrq-trigger
The system does not reboot as expected.
Fix it by calling imx_sc_wdt_set_timeout() to configure the i.MX8QXP
watchdog with a proper timeout.

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.
