Merge tag 'usb-5.2-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 5.2-rc1

  There is the usual set of:

   - USB gadget updates

   - PHY driver updates and additions

   - USB serial driver updates and fixes

   - typec updates and new chips supported

   - mtu3 driver updates

   - xhci driver updates

   - other tiny driver updates

  Nothing really interesting, just constant forward progress.

  All of these have been in linux-next for a while with no reported
  issues. The usb-gadget and usb-serial trees were merged a bit "late",
  but both of them had been in linux-next before they got merged here
  last Friday"
