max98925 audio CODEC



This device supports I2C.



Required properties:



  - compatible : "maxim,max98925"



  - vmon-slot-no : slot number used to send voltage information



  - imon-slot-no : slot number used to send current information



  - reg : the I2C address of the device for I2C



Example:



codec: max98925@1a {

	compatible = "maxim,max98925";

	vmon-slot-no = <0>;

	imon-slot-no = <2>;

	reg = <0x1a>;

};

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>;

This device supports I2C.



Required properties:

    - "maxim,max98926"

    - "maxim,max98927"

                   interleave slot.

                   MAX98925/MAX98926 slot range : 0 ~ 30,  Default : 0

                   MAX98927 slot range : 0 ~ 15,  Default : 0



  - imon-slot-no : slot number used to send current information

                   MAX98925/MAX98926 slot range : 0 ~ 30,  Default : 0

                   MAX98927 slot range : 0 ~ 15,  Default : 0
