  Revert "USB: musb: pm: don't rely fully on clock support"
  Revert "USB: musb: blackfin: pm: make it work"
  USB: uas: Use GFP_NOIO instead of GFP_KERNEL in I/O submission path
  USB: uas: Ensure we only bind to a UAS interface
  USB: uas: Rename sense pipe and sense urb to status pipe and status urb
  USB: uas: Use kzalloc instead of kmalloc
  USB: uas: Fix up the Sense IU
  usb: musb: core: kill unneeded #include's
  DA8xx: assign name to MUSB IRQ resource

  ...

Manually fix up trivial conflicts in USB Kconfig changes in:
	arch/arm/mach-omap2/Kconfig
	arch/sh/Kconfig
	drivers/usb/Kconfig
	drivers/usb/host/ehci-hcd.c
and annoying chip clock data conflicts in:
	arch/arm/mach-omap2/clock3xxx_data.c
	arch/arm/mach-omap2/clock44xx_data.c
