+Required properties:
+ - compatible : "ti,twl4030-madc-battery"
+ - capacity : battery capacity in uAh
+ - charging-calibration-data : list of voltage(mV):level(%) values
+	for charging calibration (see example)
+ - discharging-calibration-data : list of voltage(mV):level(%) values
+	for discharging calibration (see example)
+ - io-channels: Should contain IIO channel specifiers
+	for each element in io-channel-names.
+- io-channel-names: Should contain the following values:
+ * "temp" - The ADC channel for temperature reading
+ * "ichg" - The ADC channel for battery charging status
+ * "vbat" - The ADC channel to measure the battery voltage
+
+Example:
+	madc-battery {
+		compatible = "ti,twl4030-madc-battery";
+		capacity = <1200000>;
+		charging-calibration-data = <4200 100
+					     4100 75
+					     4000 55
+					     3900 25
+					     3800 5
+					     3700 2
+					     3600 1
+					     3300 0>;
