  Nothing major here just lots of little changes for new hardware and
  features. Highlights are:

   - more USB 4 support added to the thunderbolt core

   - build warning fixes all over the place

   - usb-serial driver updates and new device support

   - mtu3 driver updates

   - gadget driver updates

   - dwc3 driver updates

   - dwc2 driver updates

   - isp1760 host driver updates

   - musb driver updates
