+CS43130 DAC
+
+Required properties:
+
+  - compatible : "cirrus,cs43130"
+
+  - reg : the I2C address of the device for I2C
+
+  - VA-supply, VP-supply, VL-supply, VCP-supply, VD-supply:
+	power supplies for the device, as covered in
+	Documentation/devicetree/bindings/regulator/regulator.txt.
+
+
+Optional properties:
+
+  - reset-gpios : Active low GPIO used to reset the device
+
+  - cirrus,xtal-ibias:
+   When external MCLK is generated by external crystal
+   oscillator, CS43130 can be used to provide bias current
+   for external crystal.  Amount of bias current sent is
+   set as:
+   1 = 7.5uA
+   2 = 12.5uA
+   3 = 15uA
+
+Example:
+
+cs43130: audio-codec@30 {
+   compatible = "cirrus,cs43130";
+   reg = <0x30>;
+   reset-gpios = <&axi_gpio 54 1>;
+   VA-supply = <&dummy_vreg>;
+   VP-supply = <&dummy_vreg>;
+   VL-supply = <&dummy_vreg>;
+   VCP-supply = <&dummy_vreg>;
+   VD-supply = <&dummy_vreg>;
+   cirrus,xtal-ibias = <2>;
+   interrupt-parent = <&gpio0>;
+   interrupts = <55 8>;
+};
