[ Upstream commit ac3dbb91e0167d017f44701dd51c1efe30d0c256 ] The Synopsys Watchdog driver sets the default timeout to 30 seconds, but on some devices this is not a valid timeout. E.g. on RK3588 the actual timeout being used is 44 seconds instead. Once the watchdog is started the value is updated accordingly, but it would be better to expose a sensible timeout to userspace without the need to first start the watchdog.

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.
