this is missing the addition of the board dt binding.
(in a separate patch)

Please see how other boards are handled in the git histoy.

regulator nodes, should be like "pcie20_avdd0v85: regulator-pcie20-avdd0v85 {"

mem-supply for cpu-cores is vendor-kernel stuff (and it's the same
regulator anyway), so please
- drop those properties,
- drop the phandle

and run
make ARCH=arm64 CHECK_DTBS=y rockchip/rk3588-axon.dtb

and fix all the reported issues please.

Thanks
