 * struct bq27000_plaform_data - Platform data for bq27000 devices
 * @name: Name of the battery. If NULL the driver will fallback to "bq27000".

 *      This function should provide access to the HDQ bus the battery is

 *      The first parameter is a pointer to the battery device, the second the
 *      register to be read. The return value should either be the content of
 *      the passed register or an error value.
