BOUGH CHEN 2946910ed8 mmc: sdhci-esdhc-imx: fix HS400 timing issue 
commit de0a0decf2 upstream.

Now tuning reset will be done when the timing is MMC_TIMING_LEGACY/
MMC_TIMING_MMC_HS/MMC_TIMING_SD_HS. But for timing MMC_TIMING_MMC_HS,
we can not do tuning reset, otherwise HS400 timing is not right.

Here is the process of init HS400, first finish tuning in HS200 mode,
then switch to HS mode and 8 bit DDR mode, finally switch to HS400
mode. If we do tuning reset in HS mode, this will cause HS400 mode
lost the tuning setting, which will cause CRC error.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

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.
