This set contains a few small improvements for the imx8mm-kontron devicetrees
(patch 1 to 4) and support for a new SoM (patch 5-6, including baseboard) that
complies to the Open Standard Module (OSM) 1.0 hardware specification, size S
(https://sget.org/standards/osm).

The official naming includes "SL" (SoM-Line) or "BL" (Board-Line).
The legacy identifiers are kept in brackets and are still used in
file names and compatible strings.

From: Frieder Schrempf <frieder.schrempf@kontron.de>
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.

For some reason there is a problem with finding a DDR configuration
that works on all operating points and all LPDDR4 types used on the
SoM. Therefore the bootloader currently doesn't configure the lowest
of the three operating points. Let's also skip this in the kernel
devicetree to make sure it isn't used.

From: Frieder Schrempf <frieder.schrempf@kontron.de>
This adds support for the Kontron Electronics SL i.MX8MM OSM-S SoM
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).

From: Frieder Schrempf <frieder.schrempf@kontron.de>
This adds support for the Kontron Electronics SL i.MX8MM OSM-S SoM
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).

Wouldn't it be better to use the real signal or voltage rail names
used in the schematics?
Like it is done here as example:
https://elixir.bootlin.com/linux/v5.19-rc6/source/arch/arm64/boot/dts/freescale/imx8mn-evk.dts#L44
Or use a name that includes both information (signal + PMIC out):

Sounds like a good idea, thanks! I will try to include in the next
version of this patchset.

On the other hand, the bindings stipulate that the regulator-names
should be "^BUCK[1-6]$" and "^LDO[1-5]$". But I admit these names are
not really useful and maybe the bindings should be changed to allow
arbitrary names?

Out of curiosity, why do you prefer usbnet instead of the fec?

We don't. In imx8mm.dtsi there is:
ethernet0 = &fec1;
We only assign the alias for the second ethernet, which is the USB adapter.

As patch 6 only covers the bindings, get_maintainer.pl didn't add you or
the linux-arm-kernel list on CC. You can find the patch on the
devicetree list or on the devicetree patchwork:
https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20220713074118.14733-7-frieder@fris.de/.
I will add you to the recipients for the next iteration.

As patch 6 only covers the bindings, get_maintainer.pl didn't add you or
the linux-arm-kernel list on CC. You can find the patch on the
devicetree list or on the devicetree patchwork:
https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20220713074118.14733-7-frieder@fris.de/.
I will add you to the recipients for the next iteration.
