This adds a generic driver for platform devices. It works like the PCI driver and is based on it. This is for devices which do not have an own bus but their OHCI controller works like a PCI controller. It will be used for the Broadcom bcma and ssb USB OHCI controller.

Add PID 0x6015, corresponding to the new series of FT-X chips (FT220XD, FT201X, FT220X, FT221X, FT230X, FT231X, FT240X). They all appear as serial devices, and seem indistinguishable except for the default product string stored in their EEPROM. The baudrate generation matches FT232RL devices. Tested with a FT201X and FT230X at various baudrates (100 - 3000000).

A MCS7820 device supports two serial ports and a MCS7840 device supports four serial ports. Both devices use the same driver, but the attach function in driver was unable to correctly handle the port numbers for MCS7820 device. This problem has been fixed in this patch and this fix has been verified on x86 Linux kernel 3.2.9 with both MCS7820 and MCS7840 devices.

Adding the Pantech UML290 and all non-QDL Gobi device IDs from the qcserial driver now that we have support for shared net/QMI USB interfaces. Most of these are not yet tested with this driver, but should be mostly identical to tested devices, except for device IDs. Gobi devices provide several different interfaces (serial/net/other) using the exact same class, subclass and protocol values. This driver will only support the net/QMI function while there are other drivers supporting other device functions. The net/QMI interface number may also differ from device to device. It has been noted that all the other interfaces have additional functional descriptors, so we use that to detect the interface supported by this driver.

Some WWAN LTE/3G devices based on chipsets from Qualcomm provide near standard CDC ECM interfaces in addition to the usual serial interfaces. The Huawei E392/E398 are examples of such devices. These typically cannot be fully configured using AT commands over a serial interface. It is necessary to speak the proprietary Qualcomm MSM Interface (QMI) protocol to the device to enable the ethernet proxy functionality. The devices embed the QMI protocol in CDC on the control interface, using standard CDC commands and notifications. The do not otherwise use CDC commands for the ethernet function. This driver does therefore not need access to any other aspects of the control interface than the descriptors attached to it. Another driver, cdc-wdm, will provide userspace access to the QMI protocol independently of this driver. To facilitate this, this driver avoids binding to the control interface, and uses only the associated data interface after parsing the common CDC functional descriptors on the control interface. You will want both the cdc-wdm and option drivers as companions to this driver, to have full access to all interfaces and protocols exported by the device.
