| * Battery info for all Stryke 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. |
