The third MMC controller (MMC2) on the Allwinner A83T SoC is slightly different. It supports a wider 8-bit bus, has a dedicated controllable reset pin for eMMC, and a "new timing mode" which is supposed to deliver better signals and thus better performance. Add a compatible for this one to use the new timing mode not found in the other controllers.

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.
