|
|
* Description:
|
|
* Initialize the BQ2425x 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 driver support
|
|
*
|
|
* Input Parameters:
|
|
* config - The config structure with function pointers to read/write.
|
|
*
|
|
* Returned Value:
|
|
* A pointer to the initialized lower-half driver instance. A NULL
|
|
* pointer is returned on a failure to initialize the BQ2425x lower half.
