/****************************************************************************
* Name: sc8551_initialize
*
* Description:
* Initialize the SC8551 (pump charger) charger driver and return
* an instance of the lower-half interface that may be used with
* battery_charger_register().
*
* This is for:
* SC8551
*
* This driver requires:
*
* CONFIG_BATTERY_CHARGER - Upper half battery charger driver support
* CONFIG_I2C - I2C support
* CONFIG_I2C_SC8551 - And the driver must be explicitly selected.
*
* Input Parameters:
* i2c - An instance of the I2C interface to use to communicate with
* the SC8551
* addr - The I2C address of the SC8551 (Better be 0x66).
* 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 SC8551 lower half.
*
