Claudiu Beznea 7ea100fb50 watchdog: rzg2l_wdt: Remove reset de-assert from probe 
[ Upstream commit 064319c3fa ]

There is no need to de-assert the reset signal on probe as the watchdog
is not used prior executing start. Also, the clocks are not enabled in
probe (pm_runtime_enable() doesn't do that), thus this is another indicator
that the watchdog wasn't used previously like this. Instead, keep the
watchdog hardware in its previous state at probe (by default it is in
reset state), enable it when it is started and move it to reset state
when it is stopped. This saves some extra power when the watchdog is
unused.

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.
