+AB85000 PMIC contains a node, which contains shared
+information about the battery connected to the PMIC.
+The node has no compatible property.
+
+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";
+ }
