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. What: /sys/class/power_supply/max77693-charger/device/top_off_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 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. Valid values: - 0 - 70 (minutes), step by 10 (rounded down)
