yes please, the mail subject will be the commit title so it must be short but descriptive enough.
"dt-bindings: serial: meson: Drop" is too short.
"dt-bindings: serial: meson: Drop compatible = amlogic,meson-gx-uart" is ok but formulation is wrong,
and remove special characters like "=", "[", "]"...
The best title could be :
"dt-bindings: serial: meson: Drop legacy amlogic,meson-gx-uart compatible"
If the subject it too long, reduce it and enhance the commit message with the details.
