| 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 | |
| amended over time. | |

| 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. | |

| 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 | |

| 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) | |
