Subject: [PATCH 08/15] usb: dwc3: Make RX/TX threshold configurable
Date: Fri, 5 Jan 2018 12:14:48 -0800 [thread overview]
Message-ID: <8446dc260efb993507a219ae11815607b8e58027.1515182391.git.thinhn@synopsys.com> (raw)
In-Reply-To: <cover.1515182391.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.
