      org.freedesktop.ModemManager1.Modem.Firmware:
      @short_description: The ModemManager Firmware interface.

      This interface provides access to perform different firmware-related operations
      in the modem, including listing the available firmware images in the module and
      selecting which of them to use.

      This interface does not provide direct access to perform firmware updates in
      the device. Instead, it exposes information about the expected firmware update
      method as well as method-specific details required for the upgrade to happen.
      The actual firmware upgrade may be performed via the Linux Vendor Firmware Service
      and the <ulink url="https://fwupd.org">fwupd</ulink> daemon.

      This interface will always be available as long a the modem is considered
      valid.

        List:

        @installed: An array of dictionaries containing the properties of the installed firmware images.

        List installed firmware images.

        Firmware slots and firmware images are identified by arbitrary opaque
        strings.

        Firmware images are represented as dictionaries of properties.
        Certain properties are pre-defined, and some are required:
