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.
