mainlining shenanigans

The da9062 hw has a minimum ping cool down phase of at least 200ms. The driver takes that into account by setting the min_hw_heartbeat_ms to 300ms and the core guarantees that the hw limit is observed for the ping() calls. But the core can't guarantee the required minimum ping cool down phase if a stop() command is send immediately after the ping() command. So it is not allowed to ping the watchdog within the stop() command as the driver does. Remove the ping can be done without doubts because the watchdog gets disabled anyway and a (re)start resets the watchdog counter too.

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.
