1* mvebu (Kirkwood, Dove, Armada 370) audio controller
2
3Required properties:
4
5- compatible:
6  "marvell,kirkwood-audio" for Kirkwood platforms
7  "marvell,dove-audio" for Dove platforms
8  "marvell,armada370-audio" for Armada 370 platforms
9
10- reg: physical base address of the controller and length of memory mapped
11  region.
12
13- interrupts:
14  with "marvell,kirkwood-audio", the audio interrupt
15  with "marvell,dove-audio", a list of two interrupts, the first for
16  the data flow, and the second for errors.
17
18- clocks: one or two phandles.
19  The first one is mandatory and defines the internal clock.
20  The second one is optional and defines an external clock.
21
22- clock-names: names associated to the clocks:
23	"internal" for the internal clock
24	"extclk" for the external clock

26Example:
27
28i2s1: audio-controller@b4000 {
29	compatible = "marvell,dove-audio";
30	reg = <0xb4000 0x2210>;
31	interrupts = <21>, <22>;
32	clocks = <&gate_clk 13>;
33	clock-names = "internal";
