Required properties:

+- compatible:
+ "marvell,kirkwood-audio" for Kirkwood platforms
+ "marvell,dove-audio" for Dove 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.
