From: Frieder Schrempf <[email protected]>
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
arm64: dts: imx8mm-kontron: Adjust board and SoM model strings
arm64: dts: imx8mm-kontron: Use the VSELECT signal to switch SD card
IO voltage
arm64: dts: imx8mm-kontron: Remove low DDRC operating point
arm64: dts: imx8mm-kontron: Use voltage rail names from schematic for
PMIC regulator-names
arm64: dts: imx8mm-kontron: Add SPI NOR partition layout
arm64: dts: Add support for Kontron SL/BL i.MX8MM OSM-S

2.37.1
From: Frieder Schrempf <[email protected]>
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.

2.37.1
From: Frieder Schrempf <[email protected]>
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).

2.37.1
From: Frieder Schrempf <[email protected]>
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.

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

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