[PATCH] arm64: dts: imx8mm: add support for compulab iot gateway

From: Parthiban Nallathambi
Date: Fri May 12 2023 - 02:17:16 EST

Add support for compulab for imx8mm IoT gateway with
UCM-iMX8M-Mini SoM. IoT gateway comes with dual ethernet,
USB and IO expansion.

WLAN, Bluetooth can be part of SoM or extended over PCIE.
