Freescale i.MX audio complex with AK5558 ADC
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : "fsl,imx-audio-ak5558"
|
||||
- model : The user-visible name of this sound complex
|
||||
- audio-cpu : The phandle of CPU DAI
|
||||
- audio-codec : The phandle of the AK5558 audio ADC
|
||||
- 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 could be power supplies, AK5558 pins,
|
||||
and the jacks on the board.
|
||||
|
||||
Example:
|
||||
|
||||
sound {
|
||||
compatible = "fsl,imx-audio-ak5558";
|
||||
model = "ak5558-audio";
|
||||
audio-cpu = <&sai1>;
|
||||
audio-codec = <&codec>;
|
||||
audio-routing =
|
||||
"AIN1", "Capture",
|
||||
"AIN2", "Capture",
|
||||
"AIN3", "Capture",
|
||||
"AIN4", "Capture",
|

"AIN5", "Capture",
|
||||
"AIN6", "Capture",
|
||||
"AIN7", "Capture",
|
||||
"AIN8", "Capture";
|
||||
};
