Raul E Rangel fb1e97674a mmc: sdhci-acpi: Fix HS400 tuning for AMDI0040
[ Upstream commit 61d7437ed13906984c44697970ee792ac6271a31 ]

The AMD eMMC Controller can only use the tuned clock while in HS200 and
HS400 mode. If we switch to a different mode, we need to disable the
tuned clock. If we have previously performed tuning and switch back to
HS200 or HS400, we can re-enable the tuned clock.

Previously the tuned clock was not getting disabled when switching to
DDR52 which is part of the HS400 tuning sequence.

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.

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.
