|  | NVIDIA Tegra audio complex | 
|  |  | 
|  | Required properties: | 
|  | - compatible : "nvidia,tegra-audio-wm9712" | 
|  | - clocks : Must contain an entry for each entry in clock-names. | 
|  | See ../clocks/clock-bindings.txt for details. | 
|  | - clock-names : Must include the following entries: | 
|  | - pll_a | 
|  | - pll_a_out0 | 
|  | - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk) | 
|  | - nvidia,model : The user-visible name of this sound complex. | 
|  | - nvidia,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. Valid names for sources and | 
|  | sinks are the WM9712's pins, and the jacks on the board: |
