[PATCH 0/5] usb: dwc3: gadget: Handle streams

[Thinh Nguyen <Thinh.Nguyen@synopsys.com>]

The dwc3 driver wasn't implemented to handle streams. This series provide a few
updates to dwc3 and usb request for that:
* Introduce usb_request->is_last field
* Handle dwc3 transfer completion
* Handle dwc3 stream events

To use stream, the dwc3 driver must know which request is the last request of a
transfer. The controller uses this information to reallocate its resources for
different streams as transfers are completed. Function drivers that support
stream must indicate this via usb_request->is_last field.

Please note, I also included the patch
"usb: dwc3: gadget: Continue to process pending requests" in this series to
avoid dependency issue when applying to your git tree.
