You should list yourself as maintaining a file you add upstream, plus 
I'm pretty sure that's not Stan's current email address.

However, looking at this I think you should just add a new compat to 
Documentation/devicetree/bindings/media/qcom,msm8996-venus.yaml since 
the rest of the file is 1:1

Do not need '|' unless you need to preserve formatting.

In nested blocks, put it after the type:object, for readability.
