Migrating the driver lets us drop the watchdog misc device boilerplate and reduces size by 285 lines. It also brings us support for new functionality like CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED. This incurs a slight backwards-compatibility break, because the new kernel watchdog API doesn't support unloading modules for drivers whose watchdog hardware is reported to be running. This means following scenario will be no longer supported: - BIOS has enabled watchdog - Module is loaded and unloaded without opening watchdog - module_exit is expected to succeed and disable watchdog HW Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Link: https://lore.kernel.org/r/35d9dbf57b58c5f003cef31dc256ec2fec044524.1628525954.git-series.a.fatoum@pengutronix.de Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@linux-watchdog.org>
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.
