+=== AB8500 Fuel Gauge Driver ===
+
+AB8500 is a mixed signal multimedia and power management
+device comprising: power and energy-management-module,
+wall-charger, usb-charger, audio codec, general purpose adc,
+tvout, clock management and sim card interface.
+
+Fuel-guage support is part of energy-management-module, the other
+components of this module are:
+main-charger, usb-combo-charger and Battery temperature monitoring.
+
+The properties below describes the node for fuel guage driver.
+
+Required Properties:
+- compatible = "stericsson,ab8500-fg"
+- interface-name:
+	Name of the controller/driver which is part of energy-management-module
+- supplied-to:
+	This property shall have dependent nodes which represent other
+	energy-management-module.
+	This is a logical binding w.r.t power supply events
+	across energy-management-module drivers where-in, the
+	runtime battery properties are shared along with uevent
+	notification.
+	ref: di->fg.external_power_changed =
+		ab8500_fg_external_power_changed;
+		ab8500_fg.c
+
+	Need for this property:
+		energy-management-module driver updates power-supply properties
+		which are subset of events listed in 'enum power_supply_property',
+		ref: power_supply.h file
+		Event handler invokes power supply change notifier
+		which in-turn invokes registered power supply class call-back
+		based on the 'supplied-to' string.
+		ref:
+		power_supply_changed_work(..) ./drivers/power/power_supply_core.c
+		di->fg_psy.external_power_changed
+
+	example:
+	ab8500-fg {
+		/* dependent energy management modules */
+		supplied-to  = <&ab8500_chargalg &ab8500_usb>;
+	};
+
+	ab8500_battery_info: ab8500_bat_type {
+		battery-type = <2>;
+		thermistor-on-batctrl = <1>;
+	};
+
+Other dependent node for fuel-gauge is:
+	ab8500_battery_info: ab8500_bat_type {
+	};
+	This node will provide information on 'thermistor interface' and
+	'battery technology type' used.
+
+Properties of this node are:
+thermistor-on-batctrl:
+	A boolean value indicating thermistor interface	to battery
+
+	Note:
+	'btemp' and 'batctrl' are the pins interfaced for battery temperature
+	measurement, 'btemp' signal is used when NTC(negative temperature
+	coefficient) resister is interfaced external to battery whereas
+	'batctrl' pin is used when NTC resister is internal to battery.
+
+	e.g:
+	ab8500_battery_info: ab8500_bat_type {
+		thermistor-on-batctrl;
+	};
+	indiactes: NTC resister is internal to battery, 'batctrl' is used
+		for thermal measurement.
+
+	The absence of property 'thermal-on-batctrl' indicates
+	NTC resister is external to battery and  'btemp' signal is used
+	for thermal measurement.
+
+battery-type:
+	This shall be the battery manufacturing technology type,
+	allowed types are:
+		"UNKNOWN" "NiMH" "LION" "LIPO" "LiFe" "NiCd" "LiMn"
+	e.g:
+	ab8500_battery_info: ab8500_bat_type {
+		battery-name = "LION";
+	}
