For some devices like cameras the system 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 property for video-interface-devices called orientation, but it is limited to the requirements of video devices: Documentation/devicetree/bindings/media/video-interface-devices.yaml Add a new property for usb-devices that matches the behavior of ACPI's _PLD.
