Merge tag 'usb-4.21-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 4.21-rc1.

  All of the usual bits are in here:

  - loads of USB gadget driver updates and additions

  - new device ids

  - phy driver updates

  - xhci reworks and new features

  - typec updates

  Full details are in the shortlog.

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