WDT_MR and WDT_CR must not updated within three slow clock periods after the last ping (write to WDT_CR or WDT_MR). Ensure enough time has elapsed before writing those registers. wdt_write() waits for 4 periods to ensure at least 3 edges are seen by the IP.

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.
