commitc04ffa71ffupstream. Different modules maybe installed by the user on the eMMC connector of the odroid-c2. While the red modules are working without an issue, it seems some black modules (apparently Samsung based) are having issue at 200MHz While the tuning algorithm introduced in v4.14 enables high speed modes on every other tested designs, it seems a problem remains for this particular combination of board and eMMC module. Lowering the maximum frequency of the eMMC on this board until we can figure out a better solution.

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.
