But this CVS device still works in non-binned mode. Are the exact
limitations known? Is this CVS device used in other systems?

Staggered HDR isn't supported in upstream in any case.

One way to address this would be to set the minimum image size to some
larger, known to work size, for that CVS device in the CVS driver. This may
require changes on libcamera side, too, but that's a separate issue.
