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.
- wlf,hp-cfg: A list of headphone jack detect configuration register values.
The list must be 3 entries long.
hp-cfg[0]: HPSEL[1:0] of R48 (Additional Control 4).
hp-cfg[1]: {HPSWEN:HPSWPOL} of R24 (Additional Control 2).
hp-cfg[2]: {TOCLKSEL:TOEN} of R23 (Additional Control 1).
- wlf,gpio-cfg: A list of GPIO configuration register values.
The list must be 2 entries long.
gpio-cfg[0]: ALRCGPIO of R9 (Audio interface)
gpio-cfg[1]: {GPIOPOL:GPIOSEL[2:0]} of R48 (Additional Control 4).
Example:
wm8960: codec@1a {
compatible = "wlf,wm8960";
reg = <0x1a>;
wlf,shared-lrclk;
};
