should this not be:
                compatible = "qcom,sm8150-dcc", "qcom,dcc";

Since DCC has a dedicated SRAM, this has been named like this as
only base and ram-base are generic names. Let me know if this is
still required to be changed.

See https://patchwork.ozlabs.org/patch/1441182

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
