Hi,

general comments, I haven't disected the devicetrees yet.

When you submit a patch, we expect you to have tested it, so tere
is no need to have a separate tested-by line :-) .

please name your boards including the ninetree name, because x3568 is way
too generic, so
rk3568-ninetree-x3568 .....

Additionally, from that PDF above, it seems this is a system-on-module?
X3568CV2 + baseboard? If so, please split this into a dtsi + dts.
See all the other system-on-modules for reference.

Additionally, you'll need to have a 2nd patch to add the board to
Documentation/devicetree/bindings/arm/rockchip.yaml

And also possily a 3rd patch to add ninetree to
Documentation/devicetree/bindings/vendor-prefixes.yaml
