2016-02-29USB: serial: cp210x: add 8-bit and 32-bit register access functionsKonstantin Shkolnyy
cp210x_get_config and cp210x_set_config are cumbersome to use. This change introduces new register access functions for 8 and 32-bit values, instead of the above functions. Signed-off-by: Konstantin Shkolnyy <konstantin.shkolnyy@gmail.com> Signed-off-by: Johan Hovold <johan@kernel.org>

2016-02-29USB: cp210x: Add ID for Parrot NMEA GPS Flight RecorderVittorio Alfieri
The Parrot NMEA GPS Flight Recorder is a USB composite device consisting of hub, flash storage, and cp210x usb to serial chip. It is an accessory to the mass-produced Parrot AR Drone 2. The device emits standard NMEA messages which make the it compatible with NMEA compatible software. It was tested using gpsd version 3.11-3 as an NMEA interpreter and using the official Parrot Flight Recorder.

2015-11-16USB: qcserial: Fix support for HP lt4112 LTE/HSPA+ Gobi 4G ModemBjørn Mork
The DEVICE_HWI type was added under the faulty assumption that Huawei devices based on Qualcomm chipsets and firmware use the static USB interface numbering known from Gobi devices. But this model does not apply to Huawei devices like the HP branded lt4112 (Huawei me906e). Huawei firmwares will dynamically assign interface numbers. Functions are renumbered when the firmware is reconfigured. Fix by changing the DEVICE_HWI type to use a simplified version of Huawei's subclass + protocol scheme: Blacklisting known network interface combinations and assuming the rest are serial.

2015-11-16USB: cp210x: work around cp2108 GET_LINE_CTL bugKonstantin Shkolnyy
Add helper to access line-control register in order to work around a cp2108 GET_LINE_CTL bug. cp2108 GET_LINE_CTL returns the 16-bit value with the 2 bytes swapped. However, SET_LINE_CTL functions properly. When the driver tries to modify the register, it reads it, modifies some bits and writes back. Because the read bytes were swapped, this often results in an invalid value to be written. In turn, this causes cp2108 respond with a stall. The stall sometimes doesn't clear properly and cp2108 starts responding to following valid commands also with stalls, effectively failing.

2015-11-16USB: cp210x: relocate private data from USB interface to portKonstantin Shkolnyy
This change is preparation for implementing a cp2108 bug workaround. The workaround requires storing some private data. Right now the data is attached to the USB interface and allocated in the attach() callback. The bug detection requires USB I/O which is done easier from port_probe() callback rather than attach(). Since the USB access functions take port as a parameter, and since the private data is used exclusively by these functions, it can be allocated in port_probe(). Also, all cp210x devices have exactly 1 port per USB iterface, so moving private data from the USB interface to port is trivial.

2015-11-16USB: cp210x: flush device queues at closeKonstantin Shkolnyy
Flush all device queues at close in order to work around a cp2108 Tx queue bug. Occasionally, writing data and immediately closing the port makes cp2108 stop responding. The device has to be unplugged to clear the error. The failure is induced by shutting down the device while its Tx queue still has unsent data. This condition is avoided by issuing PURGE command from the close() callback. This change is applied to all cp210x devices. Clearing internal queues on close is generally good.

2015-10-09USB: qcserial: update comment for Sierra Wireless MC7304/MC7354David Ward
This comment is ambiguous since there are other MC73xx devices with different USB IDs. This USB ID is found in the MC7304 and MC7354. Cc: Bjørn Mork <bjorn@mork.no> Signed-off-by: David Ward <david.ward@ll.mit.edu> Signed-off-by: Johan Hovold <johan@kernel.org>
2015-10-09Revert "USB: qcserial/option: make AT URCs work for Sierra Wireless MC73xx"David Ward
This reverts commit d80c0d14183516f184a5ac88e11008ee4c7d2a2e (excluding the change to MAX_BL_NUM, which has since been removed). The qcserial driver now enables the SET_CONTROL_LINE_STATE request so that AT URCs will work. Move these devices back to the qcserial driver, which is used for other devices in this series that follow the same layout.

2015-10-09USB: qcserial: make AT URCs work for Sierra Wireless devicesDavid Ward
Three Sierra Wireless modems have been found to require the CDC ACM SET_CONTROL_LINE_STATE request on the AT port in order to receive unsolicited response codes, most recently the Dell Wireless 5808e (which is a re-branded Sierra Wireless EM7355). On the other hand, the Sierra Wireless MC7710 does not seem to need this request, but it was found to work either way. Use this request on the AT port of devices with the Sierra Wireless layout in the qcserial driver. The other modems that were moved to the option driver to work around this can now be moved back.
