Maxim Integrated MAX98373 Speaker Amplifier

This device supports I2C.

Required properties:

 - compatible : "maxim,max98373"

 - reg : the I2C address of the device.

Optional properties:

  - maxim,vmon-slot-no : slot number used to send voltage information
                   or in inteleave mode this will be used as
                   interleave slot.
                   slot range : 0 ~ 15,  Default : 0

  - maxim,imon-slot-no : slot number used to send current information
                   slot range : 0 ~ 15,  Default : 0

  - maxim,spkfb-slot-no : slot number used to send speaker feedback information
                   slot range : 0 ~ 15,  Default : 0

  - maxim,interleave-mode : For cases where a single combined channel
		   for the I/V sense data is not sufficient, the device can also be configured
		   to share a single data output channel on alternating frames.
		   In this configuration, the current and voltage data will be frame interleaved
		   on a single output channel.
                   Boolean, define to enable the interleave mode, Default : false

Example:

codec: max98373@31 {
   compatible = "maxim,max98373";
   reg = <0x31>;
   maxim,vmon-slot-no = <0>;
   maxim,imon-slot-no = <1>;
   maxim,spkfb-slot-no = <2>;
   maxim,interleave-mode;
};
