+Allwinner SUN8I audio codec
+------------------------------------
+
+On Sun8i-A33 SoCs, the audio is separated in different parts:
+	  - A DAI driver. It uses the "sun4i-i2s" driver which is
+	  documented here:
+	  Documentation/devicetree/bindings/sound/sun4i-i2s.txt
+	  - An analog part of the codec which is handled as PRCM registers.
+	  See Documentation/devicetree/bindings/sound/sun8i-codec-analog.txt
+	  - An digital part of the codec which is documented in this current
+	  binding documentation.
+	  - And finally, an audio card which links all the above components.
+	  The simple-audio card will be used.
+	  See Documentation/devicetree/bindings/sound/simple-card.txt
+
+This bindings documentation exposes Sun8i codec (digital part).
+
+Required properties:
+- compatible: must be "allwinner,sun8i-a33-codec"
+- reg: must contain the registers location and length
+- interrupts: must contain the codec interrupt
+- clocks: a list of phandle + clock-specifer pairs, one for each entry
+  in clock-names.
+- clock-names: should contain followings:
+   - "bus": the parent APB clock for this controller
+   - "mod": the parent module clock
+
+Here is an example to add a sound card and the codec binding on sun8i SoCs that
+are similar to A33 using simple-card:
+
+	sound {
+		compatible = "simple-audio-card";
+		simple-audio-card,name = "sun8i-a33-audio";
+		simple-audio-card,format = "i2s";
+		simple-audio-card,frame-master = <&link_codec>;
+		simple-audio-card,bitclock-master = <&link_codec>;
+		simple-audio-card,mclk-fs = <512>;
+		simple-audio-card,aux-devs = <&codec_analog>;
+		simple-audio-card,routing =
+				"Left DAC", "Digital Left DAC",
+				"Right DAC", "Digital Right DAC";
+
+		simple-audio-card,cpu {
+			sound-dai = <&dai>;
+		};
+
+		link_codec: simple-audio-card,codec {
+			sound-dai = <&codec>;
+		};
+
+	soc@01c00000 {
+		[...]
+
+		audio-codec@1c22e00 {
+			#sound-dai-cells = <0>;
+			compatible = "allwinner,sun8i-a33-codec";
+			reg = <0x01c22e00 0x400>;
+			interrupts = <GIC_SPI 29 IRQ_TYPE_LEVEL_HIGH>;
+			clocks = <&ccu CLK_BUS_CODEC>, <&ccu CLK_AC_DIG>;
+			clock-names = "bus", "mod";
+		};
+	};
