From: Frieder Schrempf <frieder.schrempf@kontron.de>
This set contains a few small improvements for the imx8mm-kontron devicetrees
(patch 3-7) and support for a new SoM (patch 8, including baseboard) that
complies to the Open Standard Module (OSM) 1.0 hardware specification, size S
(https://sget.org/standards/osm).
It also includes binding changes for the new board (patch 1) and a binding
change for the PCA9450 PMIC regulators (patch2).
Changes in v2:
* move binding changes to beginning of patchset
* Allow arbitrary regulator names in PCA9450 bindings
* Use voltage rail names from schematic for PMIC regulator-names
* Add SPI NOR partition layout to devicetree
* Remove unneeded header include
* Add tags
Frieder Schrempf (8):
dt-bindings: arm: fsl: Add Kontron BL i.MX8MM OSM-S board
dt-bindings: regulator: pca9450: Allow arbitrary regulator names

Instead of restricting regulator-name to non-descriptive names, allow
to use arbitrary strings. This enables us to use the name of the
voltage rail that is powered by the regulator as some board DTs
already do.

This should simply be removed from the bindings for the device, devices
have no business placing any constraint on this generic binding.

Ok, IIUC something like below should do then. I can change this in the
next iteration of this series or send it separately if the rest of the
set gets accepted as-is.

Yes, just send it any time and I can apply it as a fix.

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.

* [PATCH v2 4/8] arm64: dts: imx8mm-kontron: Use the VSELECT signal to switch SD card IO voltage

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.

This is the layout used by the bootloader. Add it to the kernel
devicetree to make the same layout available in Linux and have
the devicetrees synced.

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).

Changes in v2:
* add SPI NOR partitions
* use voltage rail names for PMIC regulator-name
* drop unused header include

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).
Signed-off-by: Frieder Schrempf <frieder.schrempf@kontron.de>

Changes in v2:
* add SPI NOR partitions
* use voltage rail names for PMIC regulator-name
* drop unused header include
