Hi Rob, i don't get this error. Is there anything i'm doing wrong here? ak@arbad:/project/opt-sw/linux-robh$ make O=../build-wega-robh/ dt_binding_check make[1]: Verzeichnis „/project/opt-sw/build-wega-robh“ wird betreten SCHEMA Documentation/devicetree/bindings/processed-schema.yaml /project/opt-sw/linux-robh/Documentation/devicetree/bindings/net/adi,adin.yaml: ignoring, error in schema 'adi,fifo-depth-bits' warning: no schema found in file: /project/opt-sw/linux-robh/Documentation/devicetree/bindings/net/adi,adin.yaml /project/opt-sw/linux-robh/Documentation/devicetree/bindings/regulator/fixed-regulator.yaml: ignoring, error in schema '0' warning: no schema found in file: /project/opt-sw/linux-robh/Documentation/devicetree/bindings/regulator/fixed-regulator.yaml CHKDT Documentation/devicetree/bindings/iio/proximity/maxbotix,mb1232.yaml CHKDT [...] But anyway i've fixed and send it out again.
