+* Allwinner A10 Codec
+
+Required properties:
+- compatible: must be one of the following compatibles:
+ - "allwinner,sun4i-a10-codec"
+ - "allwinner,sun6i-a31-codec"
+ - "allwinner,sun7i-a20-codec"
+ - "allwinner,sun8i-a23-codec"
+ - "allwinner,sun8i-h3-codec"
+ - "allwinner,sun8i-v3s-codec"
+- reg: must contain the registers location and length
+- interrupts: must contain the codec interrupt
+- dmas: DMA channels for tx and rx dma. See the DMA client binding,
+ Documentation/devicetree/bindings/dma/dma.txt
+- dma-names: should include "tx" and "rx".
+- clocks: a list of phandle + clock-specifer pairs, one for each entry
+ in clock-names.
+- clock-names: should contain the following:
+ - "apb": the parent APB clock for this controller
+ - "codec": the parent module clock
+
+Optional properties:
+- allwinner,pa-gpios: gpio to enable external amplifier
+
+Required properties for the following compatibles:
+ - "allwinner,sun6i-a31-codec"
+ - "allwinner,sun8i-a23-codec"
+ - "allwinner,sun8i-h3-codec"
+ - "allwinner,sun8i-v3s-codec"
+- resets: phandle to the reset control for this device
+- allwinner,audio-routing: A list of the connections between audio components.
+ Each entry is a pair of strings, the first being the
+ connection's sink, the second being the connection's
+ source. Valid names include:
+
+ Audio pins on the SoC:
+ "HP"
+ "HPCOM"
+ "LINEIN" (not on sun8i-v3s)
+ "LINEOUT" (not on sun8i-a23 or sun8i-v3s)
+ "MIC1"
+ "MIC2" (not on sun8i-v3s)
+ "MIC3" (sun6i-a31 only)
+
+ Microphone biases from the SoC:
+ "HBIAS"
+ "MBIAS" (not on sun8i-v3s)
+
+ Board connectors:
+ "Headphone"
+ "Headset Mic"
+ "Line In"
+ "Line Out"
+ "Mic"
+ "Speaker"
+
+Required properties for the following compatibles:
+ - "allwinner,sun8i-a23-codec"
+ - "allwinner,sun8i-h3-codec"
+ - "allwinner,sun8i-v3s-codec"
+- allwinner,codec-analog-controls: A phandle to the codec analog controls
+ block in the PRCM.
+
