For eMMC devices it is valid to only support 1.8V signaling. When vqmmc is set to a fixed 1.8V regulator the stack tries to set 3.3V initially and prints the following warning: mmc1: Switching to 3.3V signalling voltage failed Clear the MMC_SIGNAL_VOLTAGE_330 flag in case 3.3V is signaling is not available. This prevents the stack from even trying to use 3.3V signaling and avoids the above warning. Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> |

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
