Hello,
as Greg already mentioned the $subject line is very long.

So it's split into GXBB and GXL. actually it's split into GXBB, GXL and G12A

The idea here is to have "one logical change per patch". Deprecating and replacing "amlogic,meson-gx-uart" is one logical change. Adding a new compatible string is another logical change. I am hoping that this will also make it easier to find a shorter $subject line (which according to the patch submission guide [0] should be 70-75 characters: "the summary must be no more than 70-75 characters")
Best regards, Martin
