commit ec0970e0a1b2c807c908d459641a9f9a1be3e130 upstream. The iproc host eMMC/SD controller hold time does not meet the specification in the HS50 mode. This problem can be mitigated by disabling the HISPD bit; thus forcing the controller output data to be driven on the falling clock edges rather than the rising clock edges. Stable tag (v4.12+) chosen to assist stable kernel maintainers so that the change does not produce merge conflicts backporting to older kernel versions. In reality, the timing bug existed since the driver was first introduced but there is no need for this driver to be supported in kernel versions that old.

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.
