5bc21d3869 imx: kontron-sl-mx8mm: Prepare for I2C display detection in environment script
Enable the I2C bus and set a env variable for the reset GPIO of the touch
controller. This allows us to probe the panel in a script.

ba30cc2227 imx: kontron-sl-mx8mm: Add support for Kontron Electronics SoM SL i.MX8MM OSM-S
This adds support for the Kontron Electronics SoM SL i.MX8MM OSM-S
and the matching baseboard BL i.MX8MM OSM-S.

The SoM hardware complies to the Open Standard Module (OSM) 1.0
specification, size S (https://sget.org/standards/osm).

The existing board configuration for the non-OSM SoM is reused and
allows to detect the SoM variant at runtime.

8fd4c05cec imx: kontron-sl-mx8mm: Use the VSELECT signal to switch SD card IO voltage
It turns out that it is not necessary to declare the VSELECT signal as
GPIO and let the PMIC driver set it to a fixed high level. This switches
the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
accordingly.

Instead we can do it like other boards already do and simply mux the
VSELECT signal of the USDHC interface to the pin. This makes sure that
the correct voltage is selected by setting the PMIC's SD_VSEL input
to high or low accordingly.

dfbdc69c5d imx: kontron-sl-mx8mm: Adjust devicetree names, compatibles and model strings
This adjusts the names of the boards and SoMs to the official naming
used by Kontron marketing. These changes also affect devicetree
names and compatibles. The same changes have been submitted to the
Linux kernel.
