[PATCH v3 3/3] ARM: dts: stm32: Add Engicam i.Core STM32MP1 C.TOUCH 2.0 10.1" OF

[Jagan Teki]

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
- 10" LVDS Panel (SN65DSI84 DSI-LVDS bridge on SoM)

i.Core STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.

10.1" OF is a capacitive touch 10.1" Open Frame panel solutions.

i.Core STM32MP1 needs to mount on top of C.TOUCH 2.0 carrier with
pluged 10.1" OF for creating complete i.Core STM32MP1 C.TOUCH 2.0
10.1" Open Frame board.

Add support for it.
