+Subject: USB: EHCI: convert warning messages to debug-level
+
+From: Alan Stern <stern@rowland.harvard.edu>
+
+commit d16ba48774913d244c7eb894d28d8ae2c019a827 upstream.
+
+This patch (as1606) converts two warning messages in the ehci-hcd
+driver to debug messages, and adds a little extra information to each.
+
+The log messages occur when an EHCI controller takes too long (more
+than 20 ms) to turn its async or periodic schedule on or off. If this
+happens at all, it's liable to happen quite often and there's no point
+spamming the system log with these warnings. Furthermore, there's
+nothing much we can do about it when the problem happens.

+Subject: USB: ftdi_sio: add TIAO USB Multi-Protocol Adapter (TUMPA) support
+
+From: Antonio Ospite <ospite@studenti.unina.it>
+
+commit 54575b05af36959dfb6a49a3e9ca0c2b456b7126 upstream.
+
+TIAO/DIYGADGET USB Multi-Protocol Adapter (TUMPA) is an FTDI FT2232H
+based device which provides an easily accessible JTAG, SPI, I2C, serial
+breakout.
+
+http://www.diygadget.com/tiao-usb-multi-protocol-adapter-jtag-spi-i2c-serial.html
+http://www.tiaowiki.com/w/TIAO_USB_Multi_Protocol_Adapter_User%27s_Manual
+
+FTDI FT2232H provides two serial channels (A and B), but on the TUMPA
+channel A is dedicated to JTAG/SPI while channel B can be used for
+UART/RS-232: use the ftdi_jtag_quirk to expose only channel B as
+a usb-serial interface to userspace.

+
+I have no idea what I've been thinking while I was doing this in the first
+place. Now the strings are initialized properly and reported by lsusb.

+Subject: usb: gadget: make g_printer enumerate again
+
+From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+commit 5a175bb84d7344fbe5e26cf61b597129e7c80564 upstream.
+
+This was broken in 2e87edf49 ("usb: gadget: make g_printer use
+composite").
+The USB-strings were not setup properly and were not used. No function
+was added which results in an empty USB config.
+While fixing this, the interface number is now auto generated and not
+hard coded to 0.

+Subject: usb: host: xhci: Fix Null pointer dereferencing with 71c731a for non-x86 systems
+
+From: Vivek Gautam <gautam.vivek@samsung.com>
+
+commit 457a73d346187c2cc5d599072f38676f18f130e0 upstream.
+
+In 71c731a: usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware
+when extracting DMI strings (vendor or product_name) to mark them as quirk
+we may get NULL pointer in case of non-x86 systems which won't define
+CONFIG_DMI. Hence susbsequent strstr() calls crash while driver probing.
+
+So, returning 'false' here in case we get a NULL vendor or product_name.
+
+This is tested with ARM (exynos) system.
+
+This patch should be backported to stable kernels as old as 3.6, that
+contain the commit 71c731a296f1b08a3724bd1b514b64f1bda87a23 "usb: host:
+xhci: Fix Compliance Mode on SN65LVPE502CP Hardware"

+Subject: usb: otg: mxs-phy: Fix mx23 operation
+
+From: Mike Thompson <mpthompson@gmail.com>
+
+commit 363366cf61c544ea476f3d220f43a95cb03014f5 upstream.
+
+Currently mx23 fails to enumerate a USB device:
+
+[ 1.300000] hub 1-0:1.0: unable to enumerate USB device on port 1
+[ 1.520000] hub 1-0:1.0: unable to enumerate USB device on port 1
+[ 1.740000] hub 1-0:1.0: unable to enumerate USB device on port 1
+[ 1.960000] hub 1-0:1.0: unable to enumerate USB device on port 1
+[ 2.180000] hub 1-0:1.0: unable to enumerate USB device on port 1
+
+Use a kernel workqueue to asynchronously delay the setting of
+ENHOSTDISCONDETECT bit until after higher level hub connect/reset processing
+is complete. Prematurely setting the bit prevents the connection
+processing from completing and not setting it prevents disconnect from being
+detected. No delay is needed for clearing of ENHOSTDISCONDETECT.
+
+Successfully tested on mx23-olinuxino (micro, mini and maxi variants) and mx28evk.

+Subject: USB: qcaux: add Pantech vendor class match
+
+From: Bjørn Mork <bjorn@mork.no>
+
+commit c638eb2872b3af079501e7ee44cbb8a5cce9b4b5 upstream.
+
+The three Pantech devices UML190 (106c:3716), UML290 (106c:3718) and
+P4200 (106c:3721) all use the same subclasses to identify vendor
+specific functions. Replace the existing device specific entries
+with generic vendor matching, adding support for the P4200.
