The TS pin of the TPS56217 connects to the NTC resistor in the battery pack. By default the device is setup to support a 10-kohm but can also be configured to support a 100-kohm. Add a propietry to configure the connected NTC resistor. Therefore, the charger would get the wrong temperature information.
