Subject: [PATCH 3/3] arm64: dts: freescale: Add support for i.MX8QXP AI_ML board
Add support for i.MX8QXP AI_ML board from Einfochips. This board is one
of the Consumer Edition boards of the 96Boards family based on i.MX8QXP
SoC from NXP/Freescale.
The initial support includes following peripherals which are tested and
known to be working:
1. Debug serial via UART2
2. uSD
3. WiFi
4. Ethernet
More information about this board can be found in Arrow website:
