WM8960 audio CODEC
|
|
|
|
This device supports I2C only.
|
|
|
|
Required properties:
|
|
|
|
- compatible : "wlf,wm8960"
|
|
|
|
- reg : the I2C address of the device.
|
|
|
|
Optional properties:
|
|
- wlf,shared-lrclk: This is a boolean property. If present, the LRCM bit of
|
|
R24 (Additional control 2) gets set, indicating that ADCLRC and DACLRC pins
|
|
will be disabled only when ADC (Left and Right) and DAC (Left and Right)
|
|
are disabled.
|
|
When wm8960 works on synchronize mode and DACLRC pin is used to supply
|
|
frame clock, it will no frame clock for captrue unless enable DAC to enable
|
|
DACLRC pin. If shared-lrclk is present, no need to enable DAC for captrue.
|
|
|
|
- wlf,capless: This is a boolean property. If present, OUT3 pin will be
|
|
enabled and disabled together with HP_L and HP_R pins in response to jack
|
|
detect events.
|
|
|
|
Example:
|
|
|
|
codec: wm8960@1a {
|
|
compatible = "wlf,wm8960";
|
|
reg = <0x1a>;
|
|
|
|
wlf,shared-lrclk;
|
|
};
