[PATCH v2 1/3] dt-bindings: arm: stm32: Add compatible string for DH electronics STM32MP13xx DHCOR DHSBC board

[Marek Vasut]

Add DT compatible string for DH electronics STM32MP13xx DHCOR SoM and
DHSBC carrier board. This stm32mp135f-dhcor-dhsbc board is a stack of
DHCOR SoM based on STM32MP135F SoC (900MHz / crypto capabilities)
populated on DHSBC carrier board.

The SoM contains the following peripherals:
- STPMIC (power delivery)
- 512MB DDR3L memory
- eMMC and SDIO WiFi module

The DHSBC carrier board contains the following peripherals:
- Two RGMII Ethernet ports
- USB-A Host port, USB-C peripheral port, USB-C power supply plug
- Expansion connector

[PATCH v2 3/3] ARM: dts: stm32: Add support for STM32MP13xx DHCOR SoM and DHSBC board

[Marek Vasut]

This stm32mp135f-dhcor-dhsbc board is a stack of DHCOR SoM based on
STM32MP135F SoC (900MHz / crypto capabilities) populated on DHSBC
carrier board.

The SoM contains the following peripherals:
- STPMIC (power delivery)
- 512MB DDR3L memory
- eMMC and SDIO WiFi module

The DHSBC carrier board contains the following peripherals:
- Two RGMII Ethernet ports
- USB-A Host port, USB-C peripheral port, USB-C power supply plug
- Expansion connector

V2: - Fix the DT to list the right SoC/SoM/Board compatibles.
      Note that the SoM .dtsi compatible strings are not listed in
      Documentation/devicetree/bindings/arm/stm32/stm32.yaml
      which should be OK, because those should be overwritten
      by board .dts. The board .dts compatible strings are listed
      in stm32.yaml . If the SoM .dtsi compatible is not overwritten
      by board .dts, the DT validation should rightfully complain.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y st/stm32mp135f-dhcor-dhsbc.dtb' for 20240427221048.65392-1-marex@denx.de:

This should be addressed in

[PATCH v2] dt-bindings: net: broadcom-bluetooth: Add CYW43439 DT binding

It is already AB'd by Krzysztof, I just pinged that patch to figure out 
what's blocking it.

This comes from arch/arm/boot/dts/st/stm32mp131.dtsi , i.e. unrelated to 
this patch. But there is a schema for this in 
Documentation/devicetree/bindings/sound/st,stm32-sai.yaml in todays' next .

Just tested on stm32-next rebsed on v6.10-rc1) and no yaml issue reported.
