Merge tag 'xceiv-for-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes: usb: xceiv: patches for v3.9 merge window Two new PHY drivers coming here: one for Samsung, one for OMAP. Both architectures are adding USB3 support to mainline kernel. The PHY layer now allows us to have mulitple PHYs of the same type, which is necessary for platforms which provide more than one USB peripheral port. There's also a few cleanups here: removal of __dev* annotations, conversion of a cast to to_delayed_work(), and mxs-phy learns about ->set_suspend.
