This driver can be used as a subdriver of another USB driver, allowing it to export a Device Managment interface consisting of a single interrupt endpoint with no dedicated USB interface. Some devices provide a Device Management function combined with a wwan function in a single USB interface having three endpoints (bulk in/out + interrupt). If the interrupt endpoint is used exclusively for DM notifications, then this driver can support that as a subdriver provided that the wwan driver calls the appropriate entry points on probe, suspend, resume, pre_reset, post_reset and disconnect. The main driver must have full control over all interface related settings, including the needs_remote_wakeup flag. A manage_power function must be provided by the main driver. A manage_power stub doing direct flag manipulation is used in normal driver mode.
