Subject: [PATCH] usb: dwc3: gadget: Support up to max stream id
Date: Tue, 29 Sep 2020 15:26:29 -0700 [thread overview]
Message-ID: <41fcbd971c1a976e5353978172f11364a5534453.1601418253.git.Thinh.Nguyen@synopsys.com> (raw)
DWC3 IPs can use the maximum stream id (up to 2^16) specified by the
USB 3.x specs. Don't limit to stream id 2^15 only. Note that this does
not reflect the number of concurrent streams the controller handles
internally.
