Subject: [RFC PATCH 13/14] usb: devicetree: dwc3: Add property to disable mult TRB fetch
Date: Wed, 11 Dec 2019 18:50:19 -0800 [thread overview]
Message-ID: <b791f032edb8e6a739c342dbd0d2d5faa66ddfb8.1576118671.git.thinhn@synopsys.com> (raw)
In-Reply-To: <cover.1576118671.git.thinhn@synopsys.com>
DWC_usb32 has a feature where it can issue multiple TRB fetch requests.
Add a new property to limit and only do only single TRB fetch request.
