+WM8962 audio CODEC
+
+This device supports I2C only.
+
+Required properties:
+
+ - compatible : "wlf,wm8962"
+
+ - reg : the I2C address of the device.
+
+Optional properties:
+ - spk-mono: This is a boolean property. If present, the SPK_MONO bit
+ of R51 (Class D Control 2) gets set, indicating that the speaker is
+ in mono mode.
+
+ - mic-cfg : Default register value for R48 (Additional Control 4).
+ If absent, the default should be the register default.
+
+ - gpio-cfg : A list of GPIO configuration register values. The list must
+ be 6 entries long. If absent, no configuration of these registers is
+ performed. And note that only the value within [0x0, 0xffff] is valid.
+ Any other value is regarded as setting the GPIO register by its reset
+ value 0x0.
+
+Example:
+
+codec: wm8962@1a {
+ compatible = "wlf,wm8962";
+ reg = <0x1a>;
+
+ gpio-cfg = <
+ 0x0000 /* 0:Default */
+ 0x0000 /* 1:Default */
+ 0x0013 /* 2:FN_DMICCLK */
+ 0x0000 /* 3:Default */
+ 0x8014 /* 4:FN_DMICCDAT */
+ 0x0000 /* 5:Default */
+ >;
