From bb2bd7c7f3d0946acc2104db31df228d10f7b598 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 20 Oct 2020 10:32:42 +0300 Subject: dt-bindings: irqchip: ti, sci-inta: Update for unmapped event handling 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.
