Merge tag 'usb-5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH:
 "Here is the big USB/PHY driver pull request for 5.1-rc1.

  The usual set of gadget driver updates, phy driver updates, xhci
  updates, and typec additions. Also included in here are a lot of small
  cleanups and fixes and driver updates where needed.

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