For LDO5 we need to be able to check the status of the SD_VSEL input in order to know which control register is used. Read the status of the SD_VSEL signal via GPIO and use the correct register accordingly. To use this, the LDO5 node in the devicetree needs the sd-vsel-gpios property to reference the GPIO that is used to read back the SD_VSEL status internally. Please note that the SION bit in the IOMUX must be set if the signal is muxed as VSELECT and controlled by the USDHC controller.

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 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.
