Judith Mendez baa11a683d mmc: sdhci_am654: Disable HS400 for AM62P SR1.0 and SR1.1
commit d2d7a96b29 upstream.

This adds SDHCI_AM654_QUIRK_DISABLE_HS400 quirk which shall be used
to disable HS400 support. AM62P SR1.0 and SR1.1 do not support HS400
due to errata i2458 [0] so disable HS400 for these SoC revisions.

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 reStructuredText 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.
