[Download RAW message or body]
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.
