25 | * This is platform data for bq2415x chip. It contains default board |
| 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. | |
