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";
}
