MicroGEA STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.
MicroDev 2.0 is a general purpose miniature carrier board with CAN,
LTE and LVDS panel interfaces.
MicroGEA STM32MP1 needs to mount on top of this MicroDev 2.0 board
for creating complete MicroGEA STM32MP1 MicroDev 2.0 Carrier board.
Add bindings for it.

MicroGEA STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.
General features:
- STM32MP157AAC
- Up to 1GB DDR3L-800
- 512MB Nand flash
- I2S
MicroGEA STM32MP1 needs to mount on top of Engicam MicroDev carrier
boards for creating complete platform solutions.
Add support for it.

Minor question: if the stm32mp157 is soldered on Microdev boards why do
you mention it in this commit message ?
+ a minor comment bellow.

MicroDev 2.0 is a general purpose miniature carrier board with CAN,
LTE and LVDS panel interfaces.
Genaral features:
- Ethernet 10/100
- USB Type A
- Audio Out
- microSD
- LVDS panel connector
- Wifi/BT (option)
- UMTS LTE with sim connector (option)
MicroGEA STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.
MicroGEA STM32MP1 needs to mount on top of this MicroDev 2.0 board
for creating complete MicroGEA STM32MP1 MicroDev 2.0 Carrier board.
Add support for it.

Engicam C.TOUCH 2.0 is an EDIMM compliant general purpose Carrier
board.
Genaral features:
- Ethernet 10/100
- Wifi/BT
- USB Type A/OTG
- Audio Out
- CAN
- LVDS panel connector
i.Core STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.
i.Core STM32MP1 needs to mount on top of this Carrier board for
creating complete i.Core STM32MP1 C.TOUCH 2.0 board.
Add support for it.
