If the watchdog is already running (e.g.: started by bootloader) then the kernel driver should keep the watchdog active but the amlogic driver turns it off. Let the driver fix the clock rate if already active because we do not know the previous timebase value. To avoid unintentional resetting we temporarily set it to its maximum value. Then keep the enable bit if is was previously active.

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.
