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";
|
||
|
|
}
