Merge tag 'usb-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY updates from Greg KH:
 "Here's the big set of USB/PHY patches for 4.10-rc1.

  A number of new drivers are here in this set of changes. We have a new
  USB controller type "mtu3", a new usb-serial driver, and the usual
  churn in the gadget subsystem and the xhci host controller driver,
  along with a few other new small drivers added. And lots of little
  other changes all over the USB and PHY driver tree. Full details are
  in the shortlog

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