DT is supposed to contain information about the hardware, so it
should stay the same? I think there is no non-hackish way to decide

compatible would change, at a minimum.

why? I would expect it to stay the same (and the current patch uses
the same compatible strings).

Exactly, the new driver must support all the compatible strings
defined in Documentation/devicetree/bindings/serial/omap_serial.tx
(which already does as you pointed out).

Otherwise the current drivers/tty/serial/omap-serial.c could never be
removed since that would mean breaking DT backward compatibility.
