+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;
+};
