Merge tag 'xceiv-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

usb: phy: patches for v3.6 merge window

We are starting to support multiple USB phys as
we should thanks for Kishon's work. DeviceTree support
for USB PHYs won't come until discussion with DeviceTree
maintainer is finished.

Together with that series, we have one fix for twl4030
which missed a IRQF_ONESHOT annotation when requesting
a threaded IRQ without a top half handler, and removal
of an unused variable compilation warning to isp1301_omap.
