Merge tag 'usb-4.20-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 patches for 4.20-rc1

  Lots of USB changes in here, primarily in these areas:

   - typec updates and new drivers

   - new PHY drivers

   - dwc2 driver updates and additions (this old core keeps getting
     added to new devices.)

   - usbtmc major update based on the industry group coming together and
     working to add new features and performance to the driver.

   - USB gadget additions for new features

   - USB gadget configfs updates

   - chipidea driver updates

   - other USB gadget updates

   - USB serial driver updates

   - renesas driver updates

   - xhci driver updates

   - other tiny USB driver updates

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