Merge tag 'usb-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big set of USB and thunderbolt drivers for 6.18-rc1. It
  was another normal development cycle, with lots of the usual drivers
  getting updates:

   - Thunderbolt driver cleanups and additions

   - dwc3 driver updates

   - dwc2 driver updates

   - typec driver updates

   - xhci driver updates and additions

   - offload USB engine updates for better power management

   - unused tracepoint removals

   - usb gadget fixes and updates as more users start to rely on these
     drivers instead of the "old" function gadget drivers

   - new USB device ids

   - other minor driver USB driver updates

   - new USB I/O driver framework and driver additions"

  The last item, the usb i/o driver, has an i2c and gpio driver added
  through this tree. Those drivers were acked by the respective
  subsystem maintainers.

  All of these have been in linux-next for a while"

+description: |
+  The SpacemiT K1 embeds a DWC3 USB IP Core which supports Host functions
+  for USB 3.0 and DRD for USB 2.0.
+
+  Key features:
+  - USB3.0 SuperSpeed and USB2.0 High/Full/Low-Speed support
+  - Supports low-power modes (USB2.0 suspend, USB3.0 U1/U2/U3)
+  - Internal DMA controller and flexible endpoint FIFO sizing
+
+  Communication Interface:
+  - Use of PIPE3 (125MHz) interface for USB3.0 PHY
