+twl4030_madc_battery
+
+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>;
+
+ discharging-calibration-data = <4200 100
+ 4100 95
+ 4000 70
+ 3800 50
+ 3700 10
+ 3600 5
+ 3300 0>;
+ io-channels = <&twl_madc 1>,
+ <&twl_madc 10>,
+ <&twl_madc 12>;
+ io-channel-names = "temp",
+ "ichg",
+ "vbat";
+ };
