This host controller is possible to change incorrect tap if an SDIO card is used because DAT1 is used for interrupt signal on SDIO standard but the controller doesn't take care of it. So, in the worst case, this behavior causes a CRC error. To resolve the issue, this driver uses manual correction mode instead of auto correction if an SDIO card is used. Also, even if DAT1 is mismatched on an SDIO card, this driver will not change the TAP.

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.
