Most comments from PX3 1/2 apply here, too.

There is no PX5 listed on your English website (yet), but given that you
have your own rockchip/ folder for arm64 I would encourage you to rename
to px5-evb.dtb independent of any internal heritage or compatibility the
SoC has. Compare apq/ipq/msm in qcom.

Similarly suggest a px5.dtsi here.

Otherwise formally looks fine.
