* Battery info for all fleex battery types. Note that the fields
|
||
|
|
* start_charging_min/max and charging_min/max are not used for the charger.
|
||
|
|
* The effective temperature limits are given by discharging_min/max_c.

|
|
*
|

|
|
* Fuel Gauge (FG) parameters which are used for determining if the battery
|
||
|
|
* is connected, the appropriate ship mode (battery cutoff) command, and the
|
||
|
|
* charge/discharge FETs status.
|
||
|
|
*
|
||
|
|
* Ship mode (battery cutoff) requires 2 writes to the appropriate smart battery
|
||
|
|
* register. For some batteries, the charge/discharge FET bits are set when
|
||
|
|
* charging/discharging is active, in other types, these bits set mean that
|
||
|
|
* charging/discharging is disabled. Therefore, in addition to the mask for
|
||
|
|
* these bits, a disconnect value must be specified. Note that for TI fuel
|
||
|
|
* gauge, the charge/discharge FET status is found in Operation Status (0x54),
|
||
|
|
* but a read of Manufacturer Access (0x00) will return the lower 16 bits of
|
||
|
|
* Operation status which contains the FET status bits.
|
||
|
|
*
|
||
|
|
* The assumption for battery types supported is that the charge/discharge FET
|
||
|
|
* status can be read with a sb_read() command and therefore, only the register
|
||
|
|
* address, mask, and disconnect value need to be provided.
