Merge tag 'usb-4.15-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 updates for 4.15-rc1.

  There is the usual amount of gadget and xhci driver updates, along
  with phy and chipidea enhancements. There's also a lot of SPDX tags
  and license boilerplate cleanups as well, which provide some churn in
  the diffstat.

  Other major thing is the typec code that moved out of staging and into
  the "real" part of the drivers/usb/ tree, which was nice to see
  happen.

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