For some devices, such as cameras, the OS needs to know where they are mounted. ACPI has a property for this purpose, which is parsed by acpi_get_physical_device_location(): https://uefi.org/htmlspecs/ACPI_Spec_6_4_html/06_Device_Configuration/Device_Configuration.html#pld-physical-location-of-device In DT we have similar properties for video-interface-devices called orientation and rotation: Documentation/devicetree/bindings/media/video-interface-devices.yaml Add rotation and orientation for usb-devices that matches the already existing properties of video-interface-devices.
