+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;
+};
