Subject: [PATCH v5 2/8] usb: dwc3: update stream id in depcmd
Date: Sat, 15 Sep 2018 19:59:55 +0530 [thread overview]
Message-ID: <1537021801-23896-3-git-send-email-anurag.kumar.vulisha@xilinx.com> (raw)
In-Reply-To: <1537021801-23896-1-git-send-email-anurag.kumar.vulisha@xilinx.com>
For stream capable endpoints, stream id related information
needs to be updated into DEPCMD while issuing START TRANSFER.
This patch does the same.
