2016-03-09USB: cp210x: Add ID for Parrot NMEA GPS Flight RecorderVittorio Alfieri
[ Upstream commit 3c4c615d70c8cbdc8ba8c79ed702640930652a79 ] 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.

2016-03-07usb: chipidea: otg: change workqueue ci_otg as freezablePeter Chen
[ Upstream commit d144dfea8af7108f613139623e63952ed7e69c0c ] If we use USB ID pin as wakeup source, and there is a USB block device on this USB OTG (ID) cable, the system will be deadlock after system resume. The root cause for this problem is: the workqueue ci_otg may try to remove hcd before the driver resume has finished, and hcd will disconnect the device on it, then, it will call device_release_driver, and holds the device lock "dev->mutex", but it is never unlocked since it waits workqueue writeback to run to flush the block information, but the workqueue writeback is freezable, it is not thawed before driver resume has finished. When the driver (device: sd 0:0:0:0:) resume goes to dpm_complete, it tries to get its device lock "dev->mutex", but it can't get it forever, then the deadlock occurs. Below call stacks show the situation. So, in order to fix this problem, we need to change workqueue ci_otg as freezable, then the work item in this workqueue will be run after driver's resume, this workqueue will not be blocked forever like above case since the workqueue writeback has been thawed too. Tested at: i.mx6qdl-sabresd and i.mx6sx-sdb.

2016-03-07usb: dwc3: Fix assignment of EP transfer resourcesJohn Youn
[ Upstream commit c450960187f45d4260db87c7dd4fc0bceb5565d8 ] The assignement of EP transfer resources was not handled properly in the dwc3 driver. Commit aebda6187181 ("usb: dwc3: Reset the transfer resource index on SET_INTERFACE") previously fixed one aspect of this where resources may be exhausted with multiple calls to SET_INTERFACE. However, it introduced an issue where composite devices with multiple interfaces can be assigned the same transfer resources for different endpoints. This patch solves both issues. The assignment of transfer resources cannot perfectly follow the data book due to the fact that the controller driver does not have all knowledge of the configuration in advance. It is given this information piecemeal by the composite gadget framework after every SET_CONFIGURATION and SET_INTERFACE. Trying to follow the databook programming model in this scenario can cause errors. For two reasons: 1) The databook says to do DEPSTARTCFG for every SET_CONFIGURATION and SET_INTERFACE (8.1.5). This is incorrect in the scenario of multiple interfaces. 2) The databook does not mention doing more DEPXFERCFG for new endpoint on alt setting (8.1.6). The following simplified method is used instead: All hardware endpoints can be assigned a transfer resource and this setting will stay persistent until either a core reset or hibernation. So whenever we do a DEPSTARTCFG(0) we can go ahead and do DEPXFERCFG for every hardware endpoint as well. We are guaranteed that there are as many transfer resources as endpoints. This patch triggers off of the calling dwc3_gadget_start_config() for EP0-out, which always happens first, and which should only happen in one of the above conditions.

When usb_remove_hcd() is called a second time for the second xhci bus it will try to dequeue all pending urbs, and touches td_list which is already freed for that endpoint.

With this quirk applied, SSIC port is set to "unused" prior to xhci_suspend(). This may cause problem if host fails to suspend. In this case, the port is set to unused without host further entering D3, and the port will not be usable anymore.

commit e50293ef9775c5f1cf3fcc093037dd6a8c5684ea upstream. Commit 8520f38099cc ("USB: change hub initialization sleeps to delayed_work") changed the hub_activate() routine to make part of it run in a workqueue. However, the commit failed to take a reference to the usb_hub structure or to lock the hub interface while doing so. As a result, if a hub is plugged in and quickly unplugged before the work routine can run, the routine will try to access memory that has been deallocated. Or, if the hub is unplugged while the routine is running, the memory may be deallocated while it is in active use. This patch fixes the problem by taking a reference to the usb_hub at the start of hub_activate() and releasing it at the end (when the work is finished), and by locking the hub interface while the work routine is running. It also adds a check at the start of the routine to see if the hub has already been disconnected, in which nothing should be done.

commit a0e80fbd56b4573de997c9a088a33abbc1121400 upstream. The flash loader has been seen on a Telit UE910 modem. The flash loader is a bit special, it presents both an ACM and CDC Data interface but only the latter is useful. Unless a magic string is sent to the device it will disappear and the regular modem device appears instead.

2016-01-22USB: cdc_acm: Ignore Infineon Flash Loader utilityJonas Jonsson
commit f33a7f72e5fc033daccbb8d4753d7c5c41a4d67b upstream. Some modems, such as the Telit UE910, are using an Infineon Flash Loader utility. It has two interfaces, 2/2/0 (Abstract Modem) and 10/0/0 (CDC Data). The latter can be used as a serial interface to upgrade the firmware of the modem. However, that isn't possible when the cdc-acm driver takes control of the device. The following is an explanation of the behaviour by Daniele Palmas during discussion on linux-usb. "This is what happens when the device is turned on (without modifying the drivers): [155492.352031] usb 1-3: new high-speed USB device number 27 using ehci-pci [155492.485429] usb 1-3: config 1 interface 0 altsetting 0 endpoint 0x81 has an invalid bInterval 255, changing to 11 [155492.485436] usb 1-3: New USB device found, idVendor=058b, idProduct=0041 [155492.485439] usb 1-3: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [155492.485952] cdc_acm 1-3:1.0: ttyACM0: USB ACM device This is the flashing device that is caught by the cdc-acm driver. Once the ttyACM appears, the application starts sending a magic string (simple write on the file descriptor) to keep the device in flashing mode. If this magic string is not properly received in a certain time interval, the modem goes on in normal operative mode: [155493.748094] usb 1-3: USB disconnect, device number 27 [155494.916025] usb 1-3: new high-speed USB device number 28 using ehci-pci [155495.059978] usb 1-3: New USB device found, idVendor=1bc7, idProduct=0021 [155495.059983] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [155495.059986] usb 1-3: Product: 6 CDC-ACM + 1 CDC-ECM [155495.059989] usb 1-3: Manufacturer: Telit [155495.059992] usb 1-3: SerialNumber: 359658044004697 [155495.138958] cdc_acm 1-3:1.0: ttyACM0: USB ACM device [155495.140832] cdc_acm 1-3:1.2: ttyACM1: USB ACM device [155495.142827] cdc_acm 1-3:1.4: ttyACM2: USB ACM device [155495.144462] cdc_acm 1-3:1.6: ttyACM3: USB ACM device [155495.145967] cdc_acm 1-3:1.8: ttyACM4: USB ACM device [155495.147588] cdc_acm 1-3:1.10: ttyACM5: USB ACM device [155495.154322] cdc_ether 1-3:1.12 wwan0: register 'cdc_ether' at usb-0000:00:1a.7-3, Mobile Broadband Network Device, 00:00:11:12:13:14 Using the cdc-acm driver, the string, though being sent in the same way than using the usb-serial-simple driver (I can confirm that the data is passing properly since I used an hw usb sniffer), does not make the device to stay in flashing mode."

2015-12-09xhci: Workaround to get Intel xHCI reset working more reliablyRajmohan Mani
commit a5964396190d0c40dd549c23848c282fffa5d1f2 upstream. Existing Intel xHCI controllers require a delay of 1 mS, after setting the CMD_RESET bit in command register, before accessing any HC registers. This allows the HC to complete the reset operation and be ready for HC register access. Without this delay, the subsequent HC register access, may result in a system hang, very rarely. Verified CherryView / Braswell platforms go through over 5000 warm reboot cycles (which was not possible without this patch), without any xHCI reset hang.

commit 705e63d2b29c8bbf091119084544d353bda70393 upstream. There is a bit of a mess in the order of arguments to the ulpi write callback. There is int ulpi_write(struct ulpi *ulpi, u8 addr, u8 val) in drivers/usb/common/ulpi.c; struct usb_phy_io_ops { ... int (*write)(struct usb_phy *x, u32 val, u32 reg); } in include/linux/usb/phy.h. The callback registered by the musb driver has to comply to the latter, but up to now had "offset" first which effectively made the function broken for correct users. So flip the order and while at it also switch to the parameter names of struct usb_phy_io_ops's write.
