The current code dealing with calculating mmc->f_min is a bit complicated. Additionally, the attempt to set an initial clock rate should explicitly use a rate between 100KHz to 400 KHz, according the (e)MMC/SD specs, which it doesn't. Fix the problem and clean up the code by using clk_round_rate() to pick the nearest minimum rate to 400KHz (rounded down from 400kHz).

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.
