Haibo Chen 8041e7b7e7 mmc: core: sdio: hold retuning if sdio in 1-bit mode
commit 32a9cdb886 upstream.

tuning only support in 4-bit mode or 8 bit mode, so in 1-bit mode,
need to hold retuning.

Find this issue when use manual tuning method on imx93. When system
resume back, SDIO WIFI try to switch back to 4 bit mode, first will
trigger retuning, and all tuning command failed.

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.
