Implement endpoint dequeue callback function.
Without this function, uboot will hang when executing fastboot comamnd.
See following flow:
"fastboot_tx_write_str->fastboot_tx_write->usb_ep_dequeue->ep->ops->dequeue
" without implement ci_udc dequeue function, ep->ops->dequeue is NULL, then
uboot will hang.
Tested on mx6qsabresd board with fastboot enabled.
diff --git a/drivers/usb/gadget/ci_udc.c b/drivers/usb/gadget/ci_udc.c
+static int ci_ep_dequeue(struct usb_ep *_ep, struct usb_request *_req)
+ if (ci_req->req.status == -EINPROGRESS) {
+ ci_req->req.status = -ECONNRESET;
+ if (ci_req->req.complete)
+ ci_req->req.complete(_ep, _req);
+ }
Is there no need to reprogram the HW to abort the transfer?
