commit 3c4c615d70c8cbdc8ba8c79ed702640930652a79 upstream. 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 Mork1-20/+34
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.

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.

2015-08-18USB: symbolserial: Correct transferred data sizePhilipp Hachtmann1-10/+8
The scanner (here DS3508) always returns 64 bytes per urb buffer. The first byte indicates the data length used in the current buffer. There even was a comment describing this. But the comment also said that we'll send everything in the buffer to the tty layer. That means sending the actual barcode data and lots of trailing zeroes. This patch lets the driver only send the real data.

2015-07-31USB: io_ti: Add heartbeat to keep idle EP/416 ports from disconnectingPeter E. Berger1-1/+94
When using Edgeport/416 models with newer firmware (sometime after firmware version 4.80.0), idle ports are automatically bounced (disconnected and then reconnected) approximately every 60 seconds. This breaks programs (e.g: minicom) where idle periods are common, normal and expected. I confirmed with the manufacturer (Digi International) that Edgeport/416 models now ship from the factory with firmware that expects periodic "heartbeat" queries from the driver to keep idle ports alive. This patch implements heartbeat support using the mechanism Digi suggested (periodically requesting an I2C descriptor address) that appears effective on Edgeports running the newer firmware (that require it) and benign on Edgeport devices running older firmware. Since we know that Edgeport firmware version 4.80 (the version distributed in /lib/firmware/down3.bin and used for Edgeports that are either running still older versions or have no onboard non-volatile firmware image) does not require heartbeat support, this patch schedules heartbeats only on Edgeport/416 devices, and only if they are running firmware versions newer than 4.80.

2015-07-31USB: io_ti: Add firmware image sanity checksPeter E. Berger1-4/+36
Do what we can to verify that the driver's firmware image is valid (before attempting to download it to the Edgeport) by adding a new function, check_fw_sanity(), and a call to it in in download_fw(). Note: It looks like some Edgeports (models like the EP/416 with on-board E2PROM) may be able to function even if the on-disk firmware image is bad or missing, iff their local E2PROM versions are valid. But most Edgeport models (I've tried EP/1 and EP/8) do not appear to have this capability and they always rely on the on-disk firmware image. I tested an implementation that calls the new check_fw_sanity() function at the top of download_fw() and, rather than simply returning an error if the firmware image is bad or missing, it saves the result and defers the decision until later when it may find that it is running on a E2PROM-equipped device with a valid image. But I think this is messier than it is worth (adding still more messiness to the already very messy download_fw()) for such a marginal possible benefit. So, at least for now, I have chosen the much simpler approach of returning an error whenever edge_startup() fails to load an on-disk firmware image, or check_fw_sanity() indicates that it is unusable.

2015-07-31USB: io_ti: Fix firmware version handlingPeter E. Berger1-49/+65
The io_ti driver fails to download firmware to Edgeport devices such as the EP/416, even when the on-disk firmware image (/lib/firmware/edgeport/down3.bin) is more current than the version on the EP/416. The current download code is broken in a few ways. Notably it mis-uses global variables OperationalMajorVersion and OperationalMinorVersion (reading their values before they've been properly initialized and subsequently initializing them multiple times without synchronization). This patch drops the global variables and replaces the redundant calls to request_firmware()/release_firmware() in download_fw() with a single call pair in edge_startup(); the firmware image pointer is then passed to download_fw() and build_i2c_fw_hdr().
