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	  See ../clocks/clock-bindings.txt for details.
7	- clock-names : Must include the following entries:
8	  - pll_a
9	  - pll_a_out0
10	  - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
11	- nvidia,model : The user-visible name of this sound complex.
12	- nvidia,audio-routing : A list of the connections between audio components.
13	  Each entry is a pair of strings, the first being the connection's sink,
14	  the second being the connection's source. Valid names for sources and
15	  sinks are the WM9712's pins, and the jacks on the board:
