One thing here is the patch title and hence commit message.

"media: starfive:" doesn't really tell you this is a camera versus say a 
encoder/decoder.

I see you've used the name "camss" for your driver, which I think is a 
perfectly good and logical choice - however if you started to make 
commits along the lines of "media: camss" that would conflict with the 
qcom camss.

How about for starfive and qcom by the way, we do what Laurent did in

commit 3e8537b4c15172bfe1b285c3155ed5c37d523cd3
Author: Laurent Pinchart <laurent.pinchart@...asonboard.com>

     media: ti: omap3isp: Use media_pipeline_for_each_entity()

i.e. future StarFive commits for camera would be "media: starfive: 
camss" and similarly for Qualcomm "media: qualcomm: camss"

The point being the commit title namespace should be instructive and 
specific re: 3e8537b4c15172bfe1b285c3155ed5c37d523cd3
