Amlogic T7 SoCs uses the same UART controller as S4 SoCs and G12A.
There is no need for an extra compatible line in the driver, but
add T7 compatible line for documentation.

Your description is rather incorrect. This is UART on SoCs compatible
with S4, not with T7. Otherwise what do you expect to grow later when
adding more compatible devices? Just drop the description, it's kind of
obvious when done correctly (but can be misleading if done wrong).

Sorry, but S4 is already added in another way, which accepts just an
S4 compatible string.
But for T7 we need a fallback.
Could you let me know what you're asking here? Redo S4 and add T7? Or
do T7 in another different way that I didn't get?
Do you want a v6 patch series? If yes, could you be more clear about
how you want it?

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.

I can't just remove that line, as it doesn't pass the checks.
I will change it to S4.
