Sounds like a Suggested-by tag to reflect the ideas would be sensible here.

This sentence isn't relevant to this patch, so I'd drop it.
We don't need additional motivation.

You have a reference above which is enough.

"Merge very similar schemas for APDS9300 and APDS9960."
is sufficient description alongside a suggested by tag and if you like
a link tag to as above. Note however that Link is an official tag
so belongs in the tag block at the end, not inline in the text.
