Hi Rob
Thanks for the advice.
The root cause of the erroneous log message is due to missing power/clock dependencies.
Once the MTK clock/power header file is upstreamed,
we will include a reference link in the next version of the upstream series submission.
Best, Paul-pl Chen

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.
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 after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.
