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

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 [0] https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html#the-canonical-patch-format

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.
