+twl4030_madc_battery
+
+Required properties:
+ - compatible : "ti,twl4030-madc-battery"
+ - capacity-uah : battery capacity in uAh
+ - ti,volt-to-capacity-charging-map : list of voltage(mV):level(%) values
+ for charging calibration (see example)
+ - ti,volt-to-capacity-discharging-map : 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-uah = <1200000>;
+ ti,volt-to-capacity-charging-map = <4200 100>,
+ <4100 75>,
+ <4000 55>,
+ <3900 25>,
+ <3800 5>,
+ <3700 2>,
+ <3600 1>,
+ <3300 0>;
+
+ ti,volt-to-capacity-discharging-map = <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";
+ };
