Merge tag 'usb-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB and PHY updates from Greg KH:
 "Here is the big USB pull request for 4.18-rc1.

  Lots of stuff here, the highlights are:

   - phy driver updates and new additions

   - usual set of xhci driver updates

   - normal set of musb updates

   - gadget driver updates and new controllers

   - typec work, it's getting closer to getting fully out of the staging
     portion of the tree.

   - lots of minor cleanups and bugfixes.

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