Enabling the clock before accessing chip registers and disabling it afterwards does not really make sense and only adds complexity to the driver. In addition to that, a comment int the driver suggests that it does not serve a useful purpose either. "The watchdog block is of course always clocked, the clk_enable()/clk_disable() calls are mainly for performing reference counting higher up in the clock hierarchy." Just keep the clock enabled instead. Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
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.
