Use unevaluatedProperties instead of additionalProperties and add a $ref to video-interface-devices.yaml in the sensor schemas. However, that will allow all properties in video-interface-devices.yaml (which is just flash-leds and lens-focus which seem fine). If you don't want that, then you will have to split up video-interface-devices.yaml. Rob

I'll send a patch for: Documentation/devicetree/bindings/media/i2c/ovti,ov02a10.yaml:additionalProperties: false Documentation/devicetree/bindings/media/i2c/ovti,ov4689.yaml:additionalProperties: false Documentation/devicetree/bindings/media/i2c/ovti,ov5640.yaml:additionalProperties: false Documentation/devicetree/bindings/media/i2c/sony,imx214.yaml:additionalProperties: false Documentation/devicetree/bindings/media/i2c/sony,imx415.yaml:additionalProperties: false to s/additionalProperties/unevaluatedProperties/ On this binding file instead. I noticed it again specifies unevaluatedProperties: false both in the and 'endpoint' nodes, which refers to /schemas/media/video-interfaces.yaml. This allows all properties from that schema to be specified.
