+
+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 : 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 = <100232>;
+};
