[PATCH 0/3] usb: dwc3: gadget: Fix halt/clear_stall handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series fixes a couple of driver issues handling ClearFeature(halt)
request:

1) A function driver often uses set_halt() to reject a class driver protocol
command. After set_halt(), the endpoint will be stalled. It can queue new
requests while the endpoint is stalled. However, dwc3 currently drops those
requests after CLEAR_STALL. The driver should only drop started requests. Keep
the pending requests in the pending list to resume and process them after the
host issues ClearFeature(Halt) to the endpoint.

2) DWC3 should issue CLEAR_STALL command _after_ END_TRANSFER command completes.
