Daniel Beer d047ec8730 mmc: sdhci-pci-gli: increase 1.8V regulator wait
commit a1149a6c06 upstream.

Inserting an SD-card on an Intel NUC10i3FNK4 (which contains a GL9755)
results in the message:

    mmc0: 1.8V regulator output did not become stable

Following this message, some cards work (sometimes), but most cards fail
with EILSEQ. This behaviour is observed on Debian 10 running kernel
4.19.188, but also with 5.8.18 and 5.11.15.

The driver currently waits 5ms after switching on the 1.8V regulator for
it to become stable. Increasing this to 10ms gets rid of the warning
about stability, but most cards still fail. Increasing it to 20ms gets
some cards working (a 32GB Samsung micro SD works, a 128GB ADATA
doesn't). At 50ms, the ADATA works most of the time, and at 100ms both
cards work reliably.

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.
