I comment only about the description, so why touching anything else? You
did not add here T7 compatible SoCs. You added here S4 compatible SoCs.

No need. If you are going to send v6, you can as well drop the description.

This is an automated instruction, just in case, because many review tags
are being ignored. If you do not know the process, here is a short
explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tools like b4 can help
here. However, there's no need to repost patches *only* to add the tags.
The upstream maintainer will do that for acks received on the version
they apply.
