Subject: [PATCH 40/53] usb: dwc2: Set actual frame number for completed ISOC
|
||
|
|
transfer
|
||
|
|
|
||
|
|
On ISOC transfer completion, in DDMA mode, set actual frame
|
||
|
|
number returning to function driver in usb_request.
|
||
|
|
|
||
|
|
Due to core limitation, returning frame number is 11-bit wide.
