As a quick hack: add the following rule to the top-level Makefile:

%.dt.yaml: include/config/kernel.release scripts_dtc
        $(Q)$(MAKE) $(build)=Documentation/devicetree/bindings
Documentation/devicetree/bindings/processed-schema.json
        $(Q)$(MAKE) $(build)=$(dtstree) $(dtstree)/$@ CHECK_DTBS=y

Now you can run checks for a single device tree by running 'make
ARCH=arm64 ...... sdm845-db845.dy.yaml'

I don't know if it's worth including this into the upstream source tree.
