* Value resistor_sense is needed for for configuring charge and
* termination current. It it is less or equal to zero, configuring charge
* and termination current will not be possible.
*
* For automode support is needed to provide name of power supply device
* in value notify_device. Device driver must immediately report property
* POWER_SUPPLY_PROP_CURRENT_MAX when current changed.
