1	Freescale i.MX audio complex with WM8962 codec
2	
3	Required properties:
4	
5	  - compatible		: "fsl,imx-audio-wm8962"
6	
7	  - model		: The user-visible name of this sound complex
8	
9	  - ssi-controller	: The phandle of the i.MX SSI controller
10	
11	  - audio-codec		: The phandle of the WM8962 audio codec
12	
13	  - audio-routing	: A list of the connections between audio components.
14				  Each entry is a pair of strings, the first being the
15				  connection's sink, the second being the connection's
16				  source. Valid names could be power supplies, WM8962
17				  pins, and the jacks on the board:
18	
19				  Power supplies:
20				   * Mic Bias
21	
22				  Board connectors:
23				   * Mic Jack
24				   * Headphone Jack
25				   * Ext Spk
26	
27	  - mux-int-port	: The internal port of the i.MX audio muxer (AUDMUX)
28	
29	  - mux-ext-port	: The external port of the i.MX audio muxer
30	
31	Note: The AUDMUX port numbering should start at 1, which is consistent with
32	hardware manual.
33	
34	Example:
35	
36	sound {
37		compatible = "fsl,imx6q-sabresd-wm8962",
38			     "fsl,imx-audio-wm8962";
39		model = "wm8962-audio";
40		ssi-controller = <&ssi2>;
41		audio-codec = <&codec>;
42			audio-routing =
43			"Headphone Jack", "HPOUTL",
44			"Headphone Jack", "HPOUTR",
45			"Ext Spk", "SPKOUTL",
46			"Ext Spk", "SPKOUTR",
47			"MICBIAS", "AMIC",
48			"IN3R", "MICBIAS",
49			"DMIC", "MICBIAS",
50			"DMICDAT", "DMIC";
51		mux-int-port = <2>;
52		mux-ext-port = <3>;
53	};
