-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@1c00000 {
-		[...]
-
-		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";
-		};
-	};
