Pull USB / PHY updates from Greg KH:
 "Here are the big set of USB and PHY driver patches for 5.7-rc1.

  Nothing huge here, some new PHY drivers, loads of USB gadget fixes and
  updates, xhci updates, usb-serial driver updates and new device ids,
  and other minor things. Full details in the shortlog.

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