Hi,

Changes since v1:
- Reviewed-by added to the first patch from Rob
- return 0 if ti,unmapped-event-sources is not present in DT

The version of INTA within DMSS (in AM64) changed how the events from the DMAs
are handled and how sysfw is presenting these events to be used for interrupts.

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.

Regards,
Peter
