MicroGEA STM32MP1 is a STM32MP157A based Micro SoM.
MicroGEA STM32MP1 needs to mount on top of this MicroDev 2.0 board
for creating complete MicroGEA STM32MP1 MicroDev 2.0 Carrier board.
Linux dts commit details:
commit <f838dae7afd0> ("ARM: dts: stm32: Add Engicam MicroGEA STM32MP1
MicroDev 2.0 board")
Add support for it.
