Dsun8i-a33-codec.txt1 Allwinner SUN8I audio codec
2 ------------------------------------
4 On Sun8i-A33 SoCs, the audio is separated in different parts:
5 - A DAI driver. It uses the "sun4i-i2s" driver which is
7 Documentation/devicetree/bindings/sound/sun4i-i2s.txt
8 - An analog part of the codec which is handled as PRCM registers.
9 See Documentation/devicetree/bindings/sound/sun8i-codec-analog.txt
10 - An digital part of the codec which is documented in this current
12 - And finally, an audio card which links all the above components.
13 The simple-audio card will be used.
