1	* Freescale SGTL5000 Stereo Codec
2	
3	Required properties:
4	- compatible : "fsl,sgtl5000".
5	
6	- reg : the I2C address of the device
7	
8	- clocks : the clock provider of SYS_MCLK
9	
10	- micbias-resistor-k-ohms : the bias resistor to be used in kOmhs
11		The resistor can take values of 2k, 4k or 8k.
12		If set to 0 it will be off.
13		If this node is not mentioned or if the value is unknown, then
14		micbias	resistor is set to 4K.
15	
16	- micbias-voltage-m-volts : the bias voltage to be used in mVolts
17		The voltage can take values from 1.25V to 3V by 250mV steps
18		If this node is not mentionned or the value is unknown, then
19		the value is set to 1.25V.
20	
21	- VDDA-supply : the regulator provider of VDDA
22	
23	- VDDIO-supply: the regulator provider of VDDIO
24	
25	Optional properties:
26	
27	- VDDD-supply : the regulator provider of VDDD
28	
29	Example:
30	
31	codec: sgtl5000@0a {
32		compatible = "fsl,sgtl5000";
33		reg = <0x0a>;
34		clocks = <&clks 150>;
35		micbias-resistor-k-ohms = <2>;
36		micbias-voltage-m-volts = <2250>;
37		VDDA-supply = <&reg_3p3v>;
38		VDDIO-supply = <&reg_3p3v>;
39	};
