/****************************************************************************
* Name: bq25618_initialize
*
* Description:
* Initialize the BQ25618 battery driver and return an instance of the
* lower-half interface that may be used with battery_charger_register().
*
* This driver requires:
*
* CONFIG_BATTERY_CHARGER - Upper half battery charger driver support
* CONFIG_I2C - I2C support
* CONFIG_I2C_BQ25618 - And the driver must be explicitly selected.
*
* Input Parameters:
* i2c - An instance of the I2C interface to use to communicate with
* the BQ25618
* addr - The I2C address of the BQ25618 (Better be 0x6A).
* frequency - The I2C frequency
* current - The input current our power-supply can offer to charger
*
* Returned Value:
* A pointer to the initialized battery driver instance. A NULL pointer
* is returned on a failure to initialize the BQ25618 lower half.
