What: /sys/class/power/ds2760-battery.*/charge_now

Description:
This file is writeable and can be used to set the current
coloumb counter value inside the battery monitor chip. This
is needed for unavoidable corrections of aging batteries.
A userspace daemon can monitor the battery charging logic
and once the counter drops out of considerable bounds, take
appropriate action.
What: /sys/class/power/ds2760-battery.*/charge_full
Date: May 2010
KernelVersion: 2.6.35
Contact: Daniel Mack <[email protected]>
Description:
This file is writeable and can be used to set the assumed
battery 'full level'. As batteries age, this value has to be
amended over time.
