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.
