The watchdog core includes a worker function which pings the watchdog until user app starts pinging it and which also pings it if the HW require more frequent pings. Use that function instead of the dedicated timer. In the mean time, we can allow the user to change the timeout. Then change the timeout module parameter to use seconds and use the watchdog_init_timeout() core function. On some HW (eg: the 8xx), SWCRR contains bits unrelated to the watchdog which have to be preserved upon write. This driver has nothing preventing the use of the magic close, so enable it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
