-* Freescale SGTL5000 Stereo Codec
-
-Required properties:
-- compatible : "fsl,sgtl5000".
-
-- reg : the I2C address of the device
-
-- #sound-dai-cells: must be equal to 0
-
-- clocks : the clock provider of SYS_MCLK
-
-- VDDA-supply : the regulator provider of VDDA
-
-- VDDIO-supply: the regulator provider of VDDIO
-
-Optional properties:
-
-- VDDD-supply : the regulator provider of VDDD
-
-- micbias-resistor-k-ohms : the bias resistor to be used in kOhms
-	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 mentioned or the value is unknown, then
-	the value is set to 1.25V.
-
-- lrclk-strength: the LRCLK pad strength. Possible values are:
-0, 1, 2 and 3 as per the table below:
-
-VDDIO		1.8V		2.5V		3.3V
-0 = 		Disable
-1 =		1.66 mA		2.87 mA		4.02  mA
-2 =		3.33 mA		5.74 mA		8.03  mA
-3 =		4.99 mA		8.61 mA		12.05 mA
-
-- sclk-strength: the SCLK pad strength. Possible values are:
-0, 1, 2 and 3 as per the table below:
-
-VDDIO		1.8V		2.5V		3.3V
-0 = 		Disable
-1 =		1.66 mA		2.87 mA		4.02  mA
-2 =		3.33 mA		5.74 mA		8.03  mA
-3 =		4.99 mA		8.61 mA		12.05 mA
-
-Example:
-
-sgtl5000: codec@a {
-	compatible = "fsl,sgtl5000";
-	reg = <0x0a>;
-	#sound-dai-cells = <0>;
-	clocks = <&clks 150>;
-	micbias-resistor-k-ohms = <2>;
-	micbias-voltage-m-volts = <2250>;
-	VDDA-supply = <&reg_3p3v>;
-	VDDIO-supply = <&reg_3p3v>;
