[PATCH v3 1/2] dt-bindings: irqchip: ti,sci-inta: Update for unmapped event handling
From: Peter Ujfalusi
Date: Tue Oct 20 2020 - 03:32:31 EST
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.
