Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).
that's missing -pins suffix but most likely it does not match other DTS
neither. So probably was based on some old kernel.

Same problems.
