-AB85000 PMIC contains a node, which contains shared

-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.
