[ Upstream commit 982bb70517aef2225bad1d802887b733db492cc0 ] Currently the watchdog core does not initialize the last_hw_keepalive time during watchdog startup. This will cause the watchdog to be pinged immediately if enough time has passed from the system boot-up time, and some types of watchdogs like K3 RTI does not like this. To avoid the issue, setup the last_hw_keepalive time during watchdog startup.

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.
