/*
 * This is platform data for bq2415x chip. It contains default board
 * voltages and currents which can be also later configured via sysfs. If
 * value is -1 then default chip value (specified in datasheet) will be
 * used.
 *
 * 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.
