+What: /sys/class/power/ds2760-battery.*/charge_now
+Date: May 2010
+KernelVersion: 2.6.35
+Contact: Daniel Mack <daniel@caiaq.de>
+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 <daniel@caiaq.de>
+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.
