Jack Mitchell e50c6a6518 UPSTREAM: watchdog: dw_wdt: ping watchdog to reset countdown before start
Currently on an rk3288 SoC when trying to use the watchdog the SoC will
instantly reset. This is due to the watchdog countdown counter being set
to its initial value of 0x0. Reset the watchdog counter before start in
order to correctly start the countdown timer from the right position.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
