1	Freescale i.MX audio complex with SGTL5000 codec
2	
3	Required properties:
4	- compatible : "fsl,imx-audio-sgtl5000"
5	- model : The user-visible name of this sound complex
6	- ssi-controller : The phandle of the i.MX SSI controller
7	- audio-codec : The phandle of the SGTL5000 audio codec
8	- audio-routing : A list of the connections between audio components.
9	  Each entry is a pair of strings, the first being the connection's sink,
10	  the second being the connection's source. Valid names could be power
11	  supplies, SGTL5000 pins, and the jacks on the board:
12	
13	  Power supplies:
14	   * Mic Bias
15	
16	  SGTL5000 pins:
17	   * MIC_IN
18	   * LINE_IN
19	   * HP_OUT
20	   * LINE_OUT
21	
22	  Board connectors:
23	   * Mic Jack
24	   * Line In Jack
25	   * Headphone Jack
26	   * Line Out Jack
27	   * Ext Spk
28	
29	- mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
30	- mux-ext-port : The external port of the i.MX audio muxer
31	
32	Note: The AUDMUX port numbering should start at 1, which is consistent with
33	hardware manual.
34	
35	Example:
36	
37	sound {
38		compatible = "fsl,imx51-babbage-sgtl5000",
39			     "fsl,imx-audio-sgtl5000";
40		model = "imx51-babbage-sgtl5000";
41		ssi-controller = <&ssi1>;
42		audio-codec = <&sgtl5000>;
43		audio-routing =
44			"MIC_IN", "Mic Jack",
45			"Mic Jack", "Mic Bias",
46			"Headphone Jack", "HP_OUT";
47		mux-int-port = <1>;
48		mux-ext-port = <3>;
49	};
