The DMA related events are directly mapped within INTA as unmapped events in contrast to previous devices with NAVSS where the events were tied to their source devices (UDMAP, ringacc). This series adds support for handling the new version of INTA by introducing a new property: ti,unmapped-event-sources which should hold a list of phandles pointing to the sources of these unmapped events.
