+Subject: USB: add quirk for devices with broken LPM
+
+From: Alan Stern <stern@rowland.harvard.edu>
+
+commit ad87e03213b552a5c33d5e1e7a19a73768397010 upstream.
+
+Some USB device / host controller combinations seem to have problems
+with Link Power Management. For example, Steinar found that his xHCI
+controller wouldn't handle bandwidth calculations correctly for two
+video cards simultaneously when LPM was enabled, even though the bus
+had plenty of bandwidth available.
+
+This patch introduces a new quirk flag for devices that should remain
+disabled for LPM, and creates quirk entries for Steinar's devices.

+Subject: USB: cdc_acm: Ignore Infineon Flash Loader utility
+
+From: Jonas Jonsson <jonas@ludd.ltu.se>
+
+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."

+From: Jonas Jonsson <jonas@ludd.ltu.se>
+
+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.
