+* mvebu (Kirkwood, Dove, Armada 370) audio controller
+
+Required properties:
+
+- 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:
+ 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.
+ The second one is optional and defines an external clock.
+
+- clock-names: names associated to the clocks:
+ "internal" for the internal clock
+ "extclk" for the external clock
+
+Example:
+
+i2s1: audio-controller@b4000 {
+ compatible = "marvell,dove-audio";
+ reg = <0xb4000 0x2210>;
+ interrupts = <21>, <22>;
+ clocks = <&gate_clk 13>;
+ clock-names = "internal";
+};
