5Description:
6 This file is writeable and can be used to set the current
7 coloumb counter value inside the battery monitor chip. This
8 is needed for unavoidable corrections of aging batteries.
9 A userspace daemon can monitor the battery charging logic
10 and once the counter drops out of considerable bounds, take
11 appropriate action.

17Description:
18 This file is writeable and can be used to set the assumed
19 battery 'full level'. As batteries age, this value has to be
20 amended over time.

26Description:
27 This entry shows and sets the maximum time the max14577
28 charger operates in fast-charge mode. When the timer expires
29 the device will terminate fast-charge mode (charging current
30 will drop to 0 A) and will trigger interrupt.
31
32 Valid values:
33 - 5, 6 or 7 (hours),
34 - 0: disabled.

54Description:
55 This entry shows and sets the charging current threshold for
56 entering top-off charging mode. When charging current in fast
57 charge mode drops below this value, the charger will trigger
58 interrupt and start top-off charging mode.
