I followed the example given in https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/

make CHECK_DTBS=y DT_SCHEMA_FILES=trivial-devices.yaml qcom/sm8450-hdk.dtb
make CHECK_DTBS=y DT_SCHEMA_FILES=/gpio/ qcom/sm8450-hdk.dtb
----> make CHECK_DTBS=y DT_SCHEMA_FILES=qcom qcom/sm8450-hdk.dtb

Will include the yaml from next time.

Thanks
