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.

Add properties for configuring the MICBIAS pins as general purpose outputs, with some limitations: The voltage on the pin when activated may be set using another property to 2.0 V, 2.5 V or AVDD. When deactivated the pin will float.
