Merge tag 'usb-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB merge for 3.4-rc1 from Greg KH:
 "Here's the big USB merge for the 3.4-rc1 merge window.

  Lots of gadget driver reworks here, driver updates, xhci changes, some
  new drivers added, usb-serial core reworking to fix some bugs, and
  other various minor things.

  There are some patches touching arch code, but they have all been
  acked by the various arch maintainers."

+
+/*
+ * This driver supports wwan (3G/LTE/?) devices using a vendor
+ * specific management protocol called Qualcomm MSM Interface (QMI) -
+ * in addition to the more common AT commands over serial interface
+ * management
+ *
+ * QMI is wrapped in CDC, using CDC encapsulated commands on the
+ * control ("master") interface of a two-interface CDC Union
+ * resembling standard CDC ECM.  The devices do not use the control
+ * interface for any other CDC messages.  Most likely because the
+ * management protocol is used in place of the standard CDC
+ * notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE
+ *
+ * Handling a protocol like QMI is out of the scope for any driver.
+ * It can be exported as a character device using the cdc-wdm driver,
+ * which will enable userspace applications ("modem managers") to
+ * handle it.  This may be required to use the network interface
+ * provided by the driver.
+ *
+ * These devices may alternatively/additionally be configured using AT
+ * commands on any of the serial interfaces driven by the option driver
+ *
+ * This driver binds only to the data ("slave") interface to enable
+ * the cdc-wdm driver to bind to the control interface.  It still
+ * parses the CDC functional descriptors on the control interface to
+ *  a) verify that this is indeed a handled interface (CDC Union
+ *     header lists it as slave)
+ *  b) get MAC address and other ethernet config from the CDC Ethernet
+ *     header
+ *  c) enable user bind requests against the control interface, which
+ *     is the common way to bind to CDC Ethernet Control Model type
+ *     interfaces
+ *  d) provide a hint to the user about which interface is the
+ *     corresponding management interface
