earlycon is debugging tool and not suitable for mainline, wide usage. Drop.
Actually drop entire bootags and use proper stdout-path.

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).
These will bring warnings. Missing generic name,

Where is this compatible documented?
Did you run checkpatch? Did it pass without warnings?
