-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;
-};
