CB1 is Compute Module style board that plugs into Rpi board style adapter or
Manta 3D printer boards (M4P/M8P).

The board has:
	H616 SoC
	1GB of RAM
	AXP313A PMIC

And the actual boards that CB1 plugs in are just extension to it with ports and
thus are not split in DT.

Boards have:
	4x (3x for Manta boards) USB and 1 USB OTG.
	SDcard slot for loading images.
	Ethernet port wired to the internal PHY.
	2x HDMI 2.0.
	Power and Status LEDs.

Currently working:
	Booting
	USB
	UART

That's not a proper board compatible.

Does not look like supported/documented/valid property. Test your DTS
with `make dtbs_check`.

Yea my bad this was not supposed to be sent this soon.
Well either way V2 will come soon
