Adrian Hunter d51481382c mmc: sdhci-pci: Prefer SDR25 timing for High Speed mode for BYT-based Intel controllers
commit 60d53566100abde4acc5504b524bc97f89015690 upstream.

A UHS setting of SDR25 can give better results for High Speed mode.
This is because there is no setting corresponding to high speed.  Currently
SDHCI sets no value, which means zero which is also the setting for SDR12.
There was an attempt to change this in sdhci.c but it caused problems for
some drivers, so it was reverted and the change was made to sdhci-brcmstb
in commit 2fefc7c5f7d16e ("mmc: sdhci-brcmstb: Fix incorrect switch to HS
mode").  Several other drivers also do this.

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.
