Add a schema for *your* device (i.e. one that only matches the compatible string of your device). Look for anything that includes usb-device.yaml for an example. Your schema should have something like this if you want to use video-interface-devices.yaml properties: allOf: - $ref: /schemas/usb/usb-device.yaml# - $ref: /schemas/media/video-interface-devices.yaml# > > diff --git a/Documentation/devicetree/bindings/usb/usb-device.yaml b/Documentation/devicetree/bindings/usb/usb-device.yaml > index c676956810331b81f11f3624340fc3e612c98315..a44eb24c657993f88145377a4706ec419b6cd998 100644 > --- a/Documentation/devicetree/bindings/usb/usb-device.yaml > +++ b/Documentation/devicetree/bindings/usb/usb-device.yaml > @@ -44,6 +44,14 @@ properties: > - minimum: 1 > maximum: 255 > > + orientation: > + description: If present, specifies the orientation of the usb device. > + $ref: /schemas/media/video-interface-devices.yaml#/properties/orientation Again, this is generally the wrong way to add properties from another schema for your device. Above is the right way. Rob
