[PATCH v2 0/3] arm64: dts: imx8mp: add support for the ABB SoM and carrier

The board uses an ABB specific SoM from ADLink, based on NXP
i.MX8MP SoC. The SoM is used on 3 different carrier boards,
with small differences.

series is based on:
819837584309 - (tag: v6.12-rc5, origin/master, origin/HEAD) Linux 6.12-rc5

patches are now checked with

make W=1 dt_binding_check
make W=1 dtbs_check
make W=1 CHECK_DTBS=y {for each dtb introduced in this series)

as Krzysztof suggested.

Changes in v2:
- worked in comments from Krzysztof
- reworked the compatible strings for ABB imx8mp based boards
- removed unneeded dtbos and build now dtbs for each
carrierboard.
- removed user spidev entries, as I do not know the
real spi devices connected to...
- call dtb check targets as described in cover letter
and fixed warnings except warnings see below:
not fixed dtb check warnings
- pci (warning pops up for each new dtb from this patch, but
also for a lot of other boards, which are already in tree)

do not see, what I am doing wrong, also rs485 works fine
- led driver
imx8mp-aristainetos3-proton2s.dtb: /soc@0/bus@30800000/i2c@30a30000/tlc59108@40: failed to match any schema with compatible: ['ti,tlc59108']
I use the comaptible entry used in drivers/leds/leds-tlc591xx.c
Ah, may because file
Documentation/devicetree/bindings/leds/leds-tlc591xx.txt
is not converted to yaml?
- pinctrl driver
adding 'gpio-line-names' leads in a warning as this property
is not checked yet (and so a warning is dropped).
add this check in new patch
