Fabio Estevam f7d57ba8d7 watchdog: imx_sc_wdt: Fix reboot on crash
commit e56d48e92b1017b6a8dbe64923a889283733fd96 upstream.

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.

README

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.
