BTW, what are the CONFIG dependencies for this to work?
E.g. defconfig on x86_64 fails, even after enabling CONFIG_OF:
$ make dt_binding_check
SCHEMA Documentation/devicetree/bindings/processed-schema.yaml
CHKDT Documentation/devicetree/bindings/arm/primecell.yaml
...
CHKDT Documentation/devicetree/bindings/trivial-devices.yaml
make[1]: *** No rule to make target
'Documentation/devicetree/bindings/arm/primecell.example.dtb', needed
by '__build'. Stop.
Obviously it does work for arm/arm64.
Thanks!
Gr{oetje,eeting}s,
