I'm trying this series of patches for enabling /dev/video0 on sm8650 hdk but failed.
After modprobing, lsmod says just like the follwoing:

root@hdk8650:/lib/modules/6.7.0-rc3+# lsmod

This series looks for sm8550 device though, my question is that this series have been tested on the device (sm8650 hdk)? or do you expect this should work on it?

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.
