Subject: [PATCH v2 08/14] usb: dwc3: Make TX/RX threshold configurable
Date: Wed, 10 Jan 2018 13:15:05 -0800 [thread overview]
Message-ID: <6f1173cd1b3ec99f6d90c302f755cdad6ba377b2.1515618218.git.thinhn@synopsys.com> (raw)
In-Reply-To: <cover.1515618218.git.thinhn-HKixBCOQz3hWk0Htik3J/w@public.gmane.org>
DWC_usb31 periodic transfer at 48K+ bytes per interval may need
modification to the TX/RX packet threshold to achieve optimal result.
Add properties to make it configurable.
