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

[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 2/3] dt-bindings: pinctrl: sx150xq: allow gpio line naming

[Heiko Schocher]

Adding gpio-line-names property works fine for this
device node, but dtb check drops warning:

'gpio-line-names' does not match any of the regexes: '-cfg$', 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/pinctrl/semtech,sx1501q.yaml#

Allow to add property gpio-line-names for this devices.

checkpatch shows

reason for adding this patch.

No worries, this can be ignored. Warning messages can pass the limit (up
to some point).

I think gpio-line-names should always match the actual number of GPIOs
for given device. Do you have here devices with 1 gpio? This could be
further constrained in if:then sections.

I have the device with "sx150x_16_pins", see drivers/pinctrl/pinctrl-sx150x.c

I started with minItems, because I thought it is okay to allow
less names... (as I did in patch 3/3) but see now, that other drivers have
minItems = maxItems.

So I think I should add to my patch the following part:

With that, dtb checks than claim (as expected) for my 3/3 patch
from this seris:
"""
imx8mp-aristainetos3-proton2s.dtb: pinctrl@3f: gpio-line-names: ['RELAY0', 'RELAY1', 'RELAY2', 
'HEATER', 'FAN', 'SPARE', 'CLEAR', 'FAULT'] is too short
"""

So, I adapt that too in a next version of the patchset, if above
change is okay... is it?

Thanks for your review!

Heiko

Yes, but in top-level you keep widest constraints, so min 5 max 17.
