| |
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 events with similar function was originating from the UDMAP or ringacc.
The ti,unmapped-event-sources should contain phandle array to the devices in the system (typically DMA controllers) from where the unmapped events originate.
