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

[Heiko Schocher]

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)

[PATCH v2 3/3] arm64: dts: imx8mp: add aristainetos3 board support

[Heiko Schocher]

Add support for the i.MX8MP based aristainetos3 boards from ABB.

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

Hello Shawn,

removed the changes which are clear...

renamed from rename pcie0-refclk to clock-pcie0-ref

I moved compatible and reg to the beginning of the node,
as you commented this also on other places.

Should I remove newlines here too?... but looking into the example from

Documentation/devicetree/bindings/pinctrl/semtech,sx1501q.yaml

there are this newlines ... so I let this lines in... or?

and let the newlines as I did...

done.

Many thanks for your review, and sorry, for trivial fixes...

Not having newlines in middle of property list is just a style that
I prefer for IMX device trees.

One suggestion: a more succinct way to represent this would be:

brightness-levels = <0 100>;
num-interpolated-steps = <100>;
