+=== 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.
+
+Fuelgauge support is part of energy-management-modules, other
+components of this module are:
+main-charger, usb-combo-charger and battery-temperature-monitoring.
+
+The properties below describes the node for fuelgauge driver.
+
+Required Properties:
+- compatible = This shall be: "stericsson,ab8500-fg"
+- battery = Shall be battery specific information
+	Example:
+	ab8500_fg {
+		compatible = "stericsson,ab8500-fg";
+		battery	   = <&ab8500_battery>;
+	};
+
+dependent node:
+	ab8500_battery: ab8500_battery {
+	};
+	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.
+
+	Example:
+	ab8500_battery: ab8500_battery {
+		thermistor-on-batctrl;
+	};
+	indicates: 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"
+	Example:
+	ab8500_battery: ab8500_battery {

+binding for LTC2941 and LTC2943 battery gauges
+
+Both the LTC2941 and LTC2943 measure battery capacity.
+The LTC2943 is compatible with the LTC2941, it adds voltage and
+temperature monitoring, and uses a slightly different conversion
+formula for the charge counter.
+
+Required properties:
+- compatible: Should contain "ltc2941" or "ltc2943" which also indicates the
+    type of I2C chip attached.
+- reg: The 7-bit I2C address.
+- lltc,resistor-sense: The sense resistor value in milli-ohms. Can be a 32-bit
+    negative value when the battery has been connected to the wrong end of the
+    resistor.
+- lltc,prescaler-exponent: The prescaler exponent as explained in the datasheet.
+    This determines the range and accuracy of the gauge. The value is programmed
+    into the chip only if it differs from the current setting. The setting is
+    lost when the battery is disconnected.
+
+Example from the Topic Miami Florida board:
+
+	fuelgauge: ltc2943@64 {
+		compatible = "ltc2943";
+		reg = <0x64>;
+		lltc,resistor-sense = <15>;

+ - ti,input-current : Used to control and set the charger input current. This
+   value must be between 128mA and 8.064A with a 128mA step resolution. The
+   POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for
+   more information about the InputCurrent (0x3fh) register.

+   charge voltage/current.

+		reg = <0x9>;
+		ti,ac-detect-gpios = <&gpio 72 0x1>;

+TWL BCI (Battery Charger Interface)
+
+The battery charger needs to interact with the USB phy in order
+to know when charging is permissible, and when there is a connection
+or disconnection.
+
+The choice of phy cannot be configured at a hardware level, so there
+is no value in explicit configuration in device-tree.  Rather
+if there is a sibling of the BCI node which is compatible with
+"ti,twl4030-usb", then that is used to determine when and how
+use USB power for charging.
+
+Required properties:
+- compatible:
+  - "ti,twl4030-bci"
+- interrupts: two interrupt lines from the TWL SIH (secondary
+  interrupt handler) - interrupts 9 and 2.
+
+Optional properties:
+- ti,bb-uvolt: microvolts for charging the backup battery.
+- ti,bb-uamp: microamps for charging the backup battery.
+
+Examples:
+
+bci {
+   compatible = "ti,twl4030-bci";
+   interrupts = <9>, <2>;
+   ti,bb-uvolt = <3200000>;
+   ti,bb-uamp = <150>;
+};
