Merge tag 'for-v3.8-merged' of git://git.infradead.org/battery-2.6

Pull battery subsystem updates from Anton Vorontsov:
 "Highlights:

   - Two new drivers from Pali Rohár and N900 hackers: rx51_battery and
     bq2415x_charger.  The drivers are a part of a solution to replace
     the proprietary Nokia BME stack

   - Power supply core now registers devices with a thermal cooling
     subsystem, so we can now automatically throttle charging.  Thanks
     to Ramakrishna Pallala!

   - Device tree support for ab8500 and max8925_power drivers

   - Random fixups and enhancements for a bunch of drivers."

+=== 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 {
+                stericsson,battery-type = "LIPO";
+        }
