20 * struct bq27xxx_plaform_data - Platform data for bq27xxx devices
21 * @name: Name of the battery.
22 * @chip: Chip class number of this device.
23 * @read: HDQ read callback.
24 * This function should provide access to the HDQ bus the battery is
26 * The first parameter is a pointer to the battery device, the second the
27 * register to be read. The return value should either be the content of
28 * the passed register or an error value.
