The new DMA architecture introduced with AM64 introduced new event types:
unampped events.

These events are mapped within INTA in contrast to other K3 devices where

The ti,unmapped-event-sources should contain phandle array to the devices
in the system (typically DMA controllers) from where the unmapped events
