You need to describe the type. I am a bit confused whether this is a cci (so cci-control-port property?) or an interconnect (so interconnect property)... It does not look like a generic property, so you need vendor prefix. > + For details, please refer to > + Documentation/devicetree/bindings/devfreq/mtk-cci.yaml Such file does not exist.
