Hi, I'm trying this series of patches for enabling /dev/video0 on sm8650 hdk but failed.

Different SoCs so despite how close they look in version numbers, you'd expect at a minimum some clock and/or power-domain churn - even if there is a 1:1 mapping in register numbers and offsets.
We wouldn't ordinarily expect to be able to be able to move SoC versions so easily - 8550 and 8650 have similar SoC version numbers but, this is not necessarily an indicator of silicon IP block version reuse.
