+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.

+Description:
+               This file is writeable and can be used to set the assumed
+               battery 'full level'. As batteries age, this value has to be

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