+* Freescale SGTL5000 Stereo Codec
+
+Required properties:
+- compatible : "fsl,sgtl5000".
+
+- reg : the I2C address of the device
+
+- clocks : the clock provider of SYS_MCLK
+
+- micbias-resistor-k-ohms : the bias resistor to be used in kOmhs
+ The resistor can take values of 2k, 4k or 8k.
+ If set to 0 it will be off.
+ If this node is not mentioned or if the value is unknown, then
+ micbias resistor is set to 4K.
+
+- micbias-voltage-m-volts : the bias voltage to be used in mVolts
+ The voltage can take values from 1.25V to 3V by 250mV steps
+ If this node is not mentionned or the value is unknown, then
+ the value is set to 1.25V.
+
+- VDDA-supply : the regulator provider of VDDA
+
+- VDDIO-supply: the regulator provider of VDDIO
+
+Optional properties:
+
+- VDDD-supply : the regulator provider of VDDD
+
+Example:
+
+codec: sgtl5000@0a {
+ compatible = "fsl,sgtl5000";
+ reg = <0x0a>;
+ clocks = <&clks 150>;
+ micbias-resistor-k-ohms = <2>;
+ micbias-voltage-m-volts = <2250>;
+ VDDA-supply = <&reg_3p3v>;
+ VDDIO-supply = <&reg_3p3v>;
