The MMC controller can support DDR52 transfers under the new timing mode. According to the BSP kernel, the module clock has to be double the card clock, regardless of the bus width. The default timings in the hardware can be used. This also reworks the code setting the internal divider, getting rid of a extra conditional.

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.
