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 devicetree bindings to support declaring optional voltage dividers to the rail outputs of supported digital multiphase regulators. Some applications require Vout to exceed the voltage range that the Vsense pin can detect. This binding definition allows users to define the characteristics of a voltage divider placed between Vout and the Vsense pin for any rail powered by the device.
