Hello,

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

Deprecated, don't use anymore because compatible = amlogic,meson-gx-uart
don't differentiate between GXBB and GXL which have different
revisions of the UART IP. So it's split into GXBB and GXL.

actually it's split into GXBB, GXL and G12A

+              - amlogic,meson-gxbb-uart
+              - amlogic,meson-gxl-uart

+              - amlogic,meson-s4-uart

In addition to Greg's comment I suggest splitting this into two patches:
- one where the "amlogic,meson-gx-uart" compatible is marked as
deprecated (Documentation/devicetree/bindings/power/supply/bq27xxx.yaml
has an example for deprecated entries) and GXBB, GXL and G12A
compatible strings are added instead
- another one where the new S4 compatible string is added

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")

I will split the two patches in the next version.One was deprecating and 
replacing "AmLogic, Meson-GX-Uart" and the other added S4 compatible.

Best regards,
Martin
