-This device supports I2C only.
-
-Required properties:
-
-  - compatible : "wlf,wm8962"
-
-  - reg : the I2C address of the device.
-
-Optional properties:
-
-  - clocks : The clock source of the mclk
-
-  - 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:
-
-wm8962: codec@1a {
-	compatible = "wlf,wm8962";
-	reg = <0x1a>;
-	clocks = <&clks IMX6QDL_CLK_CKO>;
