+WM8971 and WM8973 audio CODEC
+
+These devices support both I2C and SPI (configured with pin strapping
+on the board).
+
+Required properties:
+
+ - compatible : "wlf,wm8971".
+ "wlf,wm8973".
+
+ - reg : the I2C address of the device for I2C, the chip select
+ number for SPI.
+
+Optional properties:
+
+ - mclk-div : Setting the CLKDIV2 bit for dividing MCLK.
+ mclk-div = <0> (Not divide & Default).
+ mclk-div = <1> (Divide by 2).
+
+ - analogue-bias : Analogue Bias optimization
+ analogue-bias = <0> (AVDD 1.8V)
+ analogue-bias = <1> (AVDD 2.5V)
+ analogue-bias = <2> (AVDD 3.3V & Default)
+
+ - headphone-en : This is a boolean property. If present, the HPSWEN bit
+ of R24 (Additional control 2) gets set, indicating that the Headphone
+ Switch is enabled.
+
+ - headphone-pol : This is a boolean property. If present, the HPSWPOL bit
+ of R24 (Additional control 2) gets set, indicating that the HPDETECT
+ high represents speaker otherwise represents headphone.
+
+Example:
+
+codec: wm8973@1a {
+ compatible = "wlf,wm8973";
+ reg = <0x1a>;
+ mclk-div = <1>;
+ analogue-bias = <0>;
+ headphone-en;
+ headphone-pol;
