I'm in trouble with the device tree binding schema of this driver too. When I run "make dt_binding_check" with $id: "http://devicetree.org/schemas/serial/silabs,si4455.yaml#" in schema, and silabs,si4455.yaml is under Documentation/devicetree/bindings/serial/, it completes successfully. When I run "make dt_binding_check" with $id: "http://devicetree.org/schemas/staging/serial/silabs,si4455.yaml#" in schema, and silabs,si4455.yaml is under Documentation/devicetree/bindings/staging/serial/, the make dt_binding_check output: Unknown file referenced: [Errno 2] No such file or directory: '/home/administrator/.local/lib/python3.6/site-packages/dtschema/schemas/staging/serial/serial.yaml' xargs: dt-doc-validate: exited with status 255; aborting Documentation/devicetree/bindings/Makefile:59: recipe for target 'Documentation/devicetree/bindings/processed-schema-examples.json' failed make[1]: *** [Documentation/devicetree/bindings/processed-schema-examples.json] Error 124 Makefile:1364: recipe for target 'dt_binding_check' failed make: *** [dt_binding_check] Error 2 When I run "make dt_binding_check" with $id: "http://devicetree.org/schemas/staging/serial/silabs,si4455.yaml#" in schema, and silabs,si4455.yaml is under Documentation/devicetree/bindings/staging/serial/, and removed $ref: "serial.yaml#". The make dt_binding_check completes successfully, but this is not a good solution. My question is, how can I use $ref: "serial.yaml" dependency in silabs,si4455.yaml, while my schema is under staging? allOf: - $ref: "serial.yaml#" If you have any suggestion that brings me to the right direction it would be great.
