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." * tag 'usb-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (302 commits) net: qmi_wwan: add support for ZTE MF820D USB: option: add ZTE MF820D usb: gadget: f_fs: Remove lock is held before freeing checks USB: option: make interface blacklist work again usb/ub: deprecate & schedule for removal the "Low Performance USB Block" driver USB: ohci-pxa27x: add clk_prepare/clk_unprepare calls USB: use generic platform driver on ath79 USB: EHCI: Add a generic platform device driver USB: OHCI: Add a generic platform device driver USB: ftdi_sio: new PID: LUMEL PD12 USB: ftdi_sio: add support for FT-X series devices USB: serial: mos7840: Fixed MCS7820 device attach problem usb: Don't make USB_ARCH_HAS_{XHCI,OHCI,EHCI} depend on USB_SUPPORT. usb gadget: fix a section mismatch when compiling g_ffs with CONFIG_USB_FUNCTIONFS_ETH USB: ohci-nxp: Remove i2c_write(), use smbus USB: ohci-nxp: Support for LPC32xx USB: ohci-nxp: Rename symbols from pnx4008 to nxp USB: OHCI-HCD: Rename ohci-pnx4008 to ohci-nxp usb: gadget: Kconfig: fix typo for 'different' usb: dwc3: pci: fix another failure path in dwc3_pci_probe() ...

+/*
+ * 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
