Or:
marvell,kirkwood-audio
marvell,dove-audio

Yes, but they are being converted over to 'marvell', I've seen some
patches posted. Also, as per
Documentation/devicetree/bindings/vendor-prefixes.txt, 'marvell' is the
right prefix for Marvell compatible strings.

Have you looked at the Samsung DT bindings for audio:
sound {
compatible = "samsung,smdk-wm8994";
samsung,i2s-controller = <&i2s0>;
samsung,audio-codec = <&wm8994>;
};
it definitely has a codec phandle reference here.
