Hello,

This patchset adds support for i.MXQXP 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:
https://www.arrow.com/en/products/imx8-ai-ml/arrow-development-tools

Thanks,
Mani

A bit confusing for the comments...

Nitpick: we usually put this two properties at the first place.
