+Maxim Integrated MAX98390 Speaker Amplifier
+
+This device supports I2C.
+
+Required properties:
+
+ - compatible : "maxim,max98390"
+
+ - reg : the I2C address of the device.
+
+Optional properties:
+
+ - maxim,temperature_calib
+   u32. The calculated temperature data was measured while doing the calibration. Data calibration : Temp / 100 * 2^12
+
+ - maxim,r0_calib
+   u32. This is r0 calibration data which was measured in factory mode.
+
+Example:
+
+codec: max98390@38 {
+   compatible = "maxim,max98390";
+   reg = <0x38>;
+   maxim,temperature_calib = <1024>;
+   maxim,r0_calib = <0x224050>;
+};
