+TI EDMA
+
+Required properties:
+- compatible : "ti,edma3"
+- ti,hwmods: Name of the hwmods associated to the EDMA
+- ti,edma-regions: Number of regions
+- ti,edma-slots: Number of slots
+
+Optional properties:
+- ti,edma-xbar-event-map: Crossbar event to channel map
+
+Example:
+
+edma: edma at 49000000 {

+	interrupt-parent = <&intc>;
+	interrupts = <12 13 14>;

+	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
+	#dma-cells = <1>;
+	dma-channels = <64>;
+	ti,edma-regions = <4>;
+	ti,edma-slots = <256>;
+	ti,edma-xbar-event-map = <1 12
