i.Core STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.
i.Core STM32MP1 needs to mount on top of this Evaluation board for
creating complete i.Core STM32MP1 EDIMM2.2 Starter Kit.
Linux dts commit details:
commit <adc0496104b6> ("ARM: dts: stm32: Add Engicam i.Core STM32MP1
EDIMM2.2 Starter Kit")
Add support for it.
