 Required properties:
 
-- compatible: "marvell,mvebu-audio"
+- compatible:
+  "marvell,kirkwood-audio" for Kirkwood platforms
+  "marvell,dove-audio" for Dove platforms
+  "marvell,armada370-audio" for Armada 370 platforms
 
 - reg: physical base address of the controller and length of memory mapped
   region.
 
-- interrupts: list of two irq numbers.
-  The first irq is used for data flow and the second one is used for errors.
+- interrupts:
+  with "marvell,kirkwood-audio", the audio interrupt
+  with "marvell,dove-audio", a list of two interrupts, the first for
+  the data flow, and the second for errors.
 
 - clocks: one or two phandles.
   The first one is mandatory and defines the internal clock.
