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.

Some Samsung devices that share the midas-audio driver use a GPIO-based approach to headset jack detection, as opposed to using the built-in jack detection provided by the wm8994 driver. This setup uses two GPIOs (one for jack detection and another for key detection) and an ADC channel for determining the jack type or button pressed. Add DT configuration values that allow for describing these setups.
