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.
What: /sys/class/power_supply/max14577-charger/device/fast_charge_timer
Date: October 2014
KernelVersion: 3.18.0
Contact: Krzysztof Kozlowski <k.kozlowski@samsung.com>
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.
What: /sys/class/power_supply/max77693-charger/device/fast_charge_timer
Date: January 2015
KernelVersion: 3.19.0
Contact: Krzysztof Kozlowski <k.kozlowski@samsung.com>
Description:
This entry shows and sets the maximum time the max77693
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:
- 4 - 16 (hours), step by 2 (rounded down)
- 0: disabled.
What: /sys/class/power_supply/max77693-charger/device/top_off_threshold_current
Date: January 2015
KernelVersion: 3.19.0
Contact: Krzysztof Kozlowski <k.kozlowski@samsung.com>
Description:
This entry shows and sets the charging current threshold for
entering top-off charging mode. When charging current in fast
charge mode drops below this value, the charger will trigger
interrupt and start top-off charging mode.
Valid values:
- 100000 - 200000 (microamps), step by 25000 (rounded down)
- 200000 - 350000 (microamps), step by 50000 (rounded down)
- 0: disabled.

Description:
This entry shows and sets the maximum time the max77693
charger operates in top-off charge mode. When the timer expires
the device will terminate top-off charge mode (charging current
will drop to 0 A) and will trigger interrupt.
