Merge tag 'usb-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

usb: patches for v3.12 merge window
All patches here have been pending on linux-usb
and sitting in linux-next for a while now.
The biggest things in this tag are:
DWC3 learned proper usage of threaded IRQ
handlers and now we spend very little time
in hardirq context.
MUSB now has proper support for BeagleBone and
Beaglebone Black.
Tegra's USB support also got quite a bit of love
and is learning to use PHY layer and generic DT
attributes.
Other than that, the usual pack of cleanups and
non-critical fixes follow.
