Subject: [PATCH 14/15] usb: dwc3: Add disabling of start_transfer failure quirk
Date: Fri, 5 Jan 2018 12:16:02 -0800 [thread overview]
Message-ID: <3c63b5f97343d276049e1d59ef2371160004b137.1515182391.git.thinhn@synopsys.com> (raw)
In-Reply-To: <cover.1515182391.git.thinhn-HKixBCOQz3hWk0Htik3J/w@public.gmane.org>
In DWC_usb31 version 1.70a-ea06 and prior needs a SW workaround for isoc
START TRANSFER command failure. However, some affected versions may have
RTL patches to fix this without a SW workaround. Add this quirk to
disable the SW workaround when it is not needed.
Synopsys STAR 9001202023: Wrong microframe number for isochronous IN
endpoints.
