26 * voltages and currents which can be also later configured via sysfs. If
27 * value is -1 then default chip value (specified in datasheet) will be
28 * used.

30 * Value resistor_sense is needed for for configuring charge and
31 * termination current. It it is less or equal to zero, configuring charge
32 * and termination current will not be possible.

34 * For automode support is needed to provide name of power supply device
35 * in value notify_device. Device driver must immediately report property
36 * POWER_SUPPLY_PROP_CURRENT_MAX when current changed.
