18 * @name: Name of the battery.
19 * @chip: Chip class number of this device.
20 * @read: HDQ read callback.
21 * This function should provide access to the HDQ bus the battery is
23 * The first parameter is a pointer to the battery device, the second the
24 * register to be read. The return value should either be the content of
25 * the passed register or an error value.
