[PATCH v2 3/3] arm64: dts: imx93: Add Engicam i.Core MX93 EDIMM 2.0 Starter Kit

From: Fabio Aiuto
Date: Thu Apr 18 2024 - 09:43:15 EST

i.Core MX93 is a NXP i.MX93 based SoM by Enigcam which
needs to be mounted on top of Engicam baseboards.

Add support for EDIMM 2.0 Starter Kit hosting
i.Core MX93.

Starter Kit main features:

2x LVDS interfaces
HDMI output
Audio out
Mic in
Micro SD card slot
USB 3.0 A port
3x USB 2.0 A port
Gb Ethernet
2x CAN bus, 3x UART interfaces
SIM card slot
M.2 KEY_B slot
