[PATCH 01/10] dt-bindings: arm: stm32: Document STM32MP23xx/STM32MP25xx DHCOS SoM and Breakout Board and DHSBC
From: Marek Vasut
Date: Sat Jul 11 2026 - 17:02:03 EST
This stm32mp25xx-dhcos-bb board is a stack of DHCOS SoM based on
STM32MP25xx SoC (1200MHz / crypto capabilities) populated on SoM
Breakout Board, the stm32mp255c-dhcos-dhsbc is the SoM populated
on DHSBC carrier board. The stm32mp23xx-dhcos-bb is a stack with
STM32MP23xx SoC.
The SoM contains the following peripherals:
- STPMIC (power delivery)
- 4GiB LPDDR4 memory
- eMMC and SDIO WiFi module
The Breakout Board carrier board contains the following peripherals:
- USB-C peripheral port, power supply plug
The DHSBC carrier board contains the following peripherals:
- Two RGMII Ethernet ports
- MicroSD slot
- LVDS connector
- MIPI CSI2 connector
- USB-A Host port, USB-C power supply plug
- USB-C / DP port
- Expansion connector
