From what I can see all boards currently supported (and those in this series) are having the RK3528A version of the SoC. I didn't follow the development here, but there are differences - I did a quick compare of the datasheets of those two SoC versions - it looks like RK3528 version has USB3-DRD controller, while RK3528A has USB3 host-only controller. Also it seems to have different video codec IPs and the DRAM controller additionally supports LPDDR4X. I guess it would be good to discuss this before this series is merged, because re-naming *.dts files after they have been in a release is somewhat impossible.
