There are many factors affecting the clock phase, including clock rate, temperature, logic voltage and silicon process, etc. But clock rate is the most significant one here, and the driver should be aware of the change of the clock rate. As mmc controller need a fixed phase after tuning was completed, at least before explicitly doing re-tune, so this patch try to restore the clock phase by monitoring the event of rate change.

README
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.
