This is done by setting the DSS DMA orderID to greater than 7. Before setting up the QoS, the ORDERID needs to be mapped to VBUSM sources using setup_navss_nb() function call that sets the threadmap for NBSS registers. (Section 10.2.10.1.2 "NB Parameters" in TRM[0]) Section 3.3.2 "Quality of Service (QoS)" in the TRM[0] provide more details.
