5- compatible:
6 "marvell,kirkwood-audio" for Kirkwood platforms
7 "marvell,dove-audio" for Dove platforms

10- interrupts: list of two irq numbers.
11 The first irq is used for data flow and the second one is used for errors.
12- interrupts:
13 with "marvell,kirkwood-audio", the audio interrupt
14 with "marvell,dove-audio", a list of two interrupts, the first for
15 the data flow, and the second for errors.
12
13- clocks: one or two phandles.
14 The first one is mandatory and defines the internal clock.
15 The second one is optional and defines an external clock.
16
17- clock-names: names associated to the clocks:
18 "internal" for the internal clock
19 "extclk" for the external clock
