+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;
+};
