+max98926 audio CODEC
+
+This device supports I2C.
+
+Required properties:
+
+  - compatible : "maxim,max98926"
+
+  - vmon-slot-no : slot number used to send voltage information
+                   or in inteleave mode this will be used as
+                   interleave slot.
+
+  - imon-slot-no : slot number used to send current information
+
+  - interleave-mode : When using two MAX98926 in a system it is
+                      possible to create ADC data that that will
+                      overflow the frame size. Digital Audio Interleave
+                      mode provides a means to output VMON and IMON data
+                      from two devices on a single DOUT line when running
+                      smaller frames sizes such as 32 BCLKS per LRCLK or
+                      48 BCLKS per LRCLK.
+
+  - reg : the I2C address of the device for I2C
+
+Example:
+
+codec: max98926@1a {
+   compatible = "maxim,max98926";
+   vmon-slot-no = <0>;
+   imon-slot-no = <2>;
+   reg = <0x1a>;
+};
