Subject: [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@...us@...00000/i2c@...30000/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
    dt-bindings: pinctrl: sx150xq: allow gpio line naming
    in v2
