This is the initial series to support Engicam MicroGEA STM32MP1
SoM and it's associated carrier board dts(i) support.

MicroGEA STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.

MicroGEA STM32MP1 needs to mount on top of Engicam carrier boards for
creating complete platform boards.

Possible carrier boards are,
- MicroDev 2.0
- MicroDev 7" Open Frame.

Any inputs?
Jagan.

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.

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.

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.

7" OF is a capacitive touch 7" Open Frame panel solutions.

MicroGEA STM32MP1 needs to mount on top of MicroDev 2.0 board with
pluged 7" OF for creating complete MicroGEA STM32MP1 MicroDev 2.0
7" Open Frame Solution board.

Add bindings for it.

7" OF is a capacitive touch 7" Open Frame panel solutions with
- 7" AUO B101AW03 LVDS panel
- EDT, FT5526 Touch

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 MicroDev 2.0 board with
pluged 7" OF for creating complete MicroGEA STM32MP1 MicroDev 2.0
7" Open Frame Solution board.

Add support for it.

If STM32MP157AAC is soldered onto this board, you should include SoC 
dtsi here and no into MicroDev 2.0 board. No ?

+#include "stm32mp15-pinctrl.dtsi"
+#include "stm32mp15xxaa-pinctrl.dtsi"

If STM32MP157AAC is soldered onto this board, you should include SoC 
dtsi here and no into MicroDev 2.0 board. No ?

+#include "stm32mp15-pinctrl.dtsi"
+#include "stm32mp15xxaa-pinctrl.dtsi"
