Merge tag 'usb-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY updates from Greg KH:
 "Here is the big set of USB and PHY driver patches for 4.17-rc1.

  Lots of USB typeC work happened this round, with code moving from the
  staging directory into the "real" part of the kernel, as well as new
  infrastructure being added to be able to handle the different types of
  "roles" that typeC requires.

  There is also the normal huge set of USB gadget controller and driver
  updates, along with XHCI changes, and a raft of other tiny fixes all
  over the USB tree. And the PHY driver updates are merged in here as
  well as they interacted with the USB drivers in some places.

  All of these have been in linux-next for a while with no reported
  issues"
