That's not a correct compatible for the board. Add new, correct
compatible (with vendor prefix) and document it in the bindings.

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

Only lowercase, no underscores in node names.
