1	NVIDIA Tegra audio complex
2	
3	Required properties:
4	- compatible : "nvidia,tegra-audio-wm9712"
5	- clocks : Must contain an entry for each entry in clock-names.
6	- clock-names : Must include the following entries:
7	  "pll_a" (The Tegra clock of that name),
8	  "pll_a_out0" (The Tegra clock of that name),
9	  "mclk" (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
10	- nvidia,model : The user-visible name of this sound complex.
11	- nvidia,audio-routing : A list of the connections between audio components.
12	  Each entry is a pair of strings, the first being the connection's sink,
13	  the second being the connection's source. Valid names for sources and
14	  sinks are the WM9712's pins, and the jacks on the board:

18	  * MONOOUT
19	  * HPOUTL
20	  * HPOUTR
21	  * LOUT2
22	  * ROUT2
23	  * OUT3
24	  * LINEINL

32	  Board connectors:
33	
34	  * Headphone
35	  * LineIn
36	  * Mic
37	
38	- nvidia,ac97-controller : The phandle of the Tegra AC97 controller

46		nvidia,model = "Toradex Colibri T20";
47	
48		nvidia,audio-routing =
49			"Headphone", "HPOUTL",
50			"Headphone", "HPOUTR",
51			"LineIn", "LINEINL",
52			"LineIn", "LINEINR",
53			"Mic", "MIC1";
54	
55		nvidia,ac97-controller = <&ac97>;
56	
57		clocks = <&tegra_car 112>, <&tegra_car 113>, <&tegra_car 93>;
58		clock-names = "pll_a", "pll_a_out0", "mclk";
