Note: my patch to add 'starfive' to vendor-prefixes.yaml was applied by
Rob back on June 2:
https://lore.kernel.org/linux-devicetree/20210602163200.GA3513985@robh.at.kernel.org/

I ran dt_binding_check and dtbs_check: 

  $ make -j8 ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- dt_binding_check \
  DT_SCHEMA_FILES=Documentation/devicetree/bindings/riscv/starfive.yaml 
  CHKDT   Documentation/devicetree/bindings/processed-schema-examples.json
  SCHEMA  Documentation/devicetree/bindings/processed-schema-examples.json
  DTC     Documentation/devicetree/bindings/riscv/starfive.example.dt.yaml
  CHECK   Documentation/devicetree/bindings/riscv/starfive.example.dt.yaml

  $ make -j8 ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- dtbs_check \
  DT_SCHEMA_FILES=Documentation/devicetree/bindings/riscv/starfive.yaml
  SCHEMA  Documentation/devicetree/bindings/processed-schema.json
  DTC     arch/riscv/boot/dts/starfive/jh7100-beaglev-starlight.dt.yaml
  CHECK   arch/riscv/boot/dts/starfive/jh7100-beaglev-starlight.dt.yaml

The files jh7100.dtsi and jh7100-beaglev-starlight.dts are in the
process of being cleaned up for submission. The current downstream is:
