+Freescale Generic ASoC Sound Card with ASRC support
+
+The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
+SoCs connecting with external CODECs.
+
+The idea of this generic sound card is a bit like ASoC Simple Card. However,
+for Freescale SoCs (especially those released in recent years), most of them
+have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
+this is a specific feature that might be painstakingly controlled and merged
+into the Simple Card.
+
+So having this generic sound card allows all Freescale SoC users to benefit
+from the simplification of a new card support and the capability of the wide
+sample rates support through ASRC.
+
+Note: The card is initially designed for those sound cards who use I2S and
+ PCM DAI formats. However, it'll be also possible to support those non
+ I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as long
+ as the driver has been properly upgraded.
+
+
+The compatible list for this generic sound card currently:
+ "fsl,imx-audio-cs42888"
+
+ "fsl,imx-audio-wm8962"
+ (compatible with Documentation/devicetree/bindings/sound/imx-audio-wm8962.txt)
+
+ "fsl,imx-audio-sgtl5000"
+ (compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)
+
+Required properties:
+
+ - compatible : Contains one of entries in the compatible list.
+
+ - model : The user-visible name of this sound complex
+
+ - audio-cpu : The phandle of an CPU DAI controller
+
+ - audio-codec : The phandle of an audio codec
+
+ - 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. There're a few pre-designed board connectors:
+ * Line Out Jack
+ * Line In Jack
+ * Headphone Jack
+ * Mic Jack
+ * Ext Spk
+ * AMIC (stands for Analog Microphone Jack)
+ * DMIC (stands for Digital Microphone Jack)
+
+ Note: The "Mic Jack" and "AMIC" are redundant while
+ coexsiting in order to support the old bindings
+ of wm8962 and sgtl5000.
+
+Optional properties:
+
+ - audio-asrc : The phandle of ASRC. It can be absent if there's no
+ need to add ASRC support via DPCM.
+
+Example:
+sound-cs42888 {
+ compatible = "fsl,imx-audio-cs42888";
+ model = "cs42888-audio";
+ audio-cpu = <&esai>;
+ audio-asrc = <&asrc>;
+ audio-codec = <&cs42888>;
+ audio-routing =
+ "Line Out Jack", "AOUT1L",
+ "Line Out Jack", "AOUT1R",

+ "AIN2L", "Line In Jack",
