Since the file is already named "...-j784s4-j742s2-...", wouldn't it be
better to add J742S2 and the link to its TRM here itself rather than
adding it in patch 4/5?

Since this is a new file and not a moved file, should it simply be "2024"?

Since SERDES2 lies in the above range, to be techincally correct, the
above range should be split up to move SERDES2 out of the common file.

PCIe2 and PCIe3 should be dropped from the common file.

Here, you have mentioned J742S2 as well, so to keep it consistent,
J742S2 should be mentioned in the "k3-j784s4-j742s2-common.dtsi" file as
well as I have indicated above.

Since this is a new file and not a renamed file, shouldn't it be "2024"?
