1	What:		/sys/class/power/ds2760-battery.*/charge_now
2	Date:		May 2010
3	KernelVersion:	2.6.35
4	Contact:	Daniel Mack <daniel@caiaq.de>
5	Description:
6			This file is writeable and can be used to set the current
7			coloumb counter value inside the battery monitor chip. This
8			is needed for unavoidable corrections of aging batteries.
9			A userspace daemon can monitor the battery charging logic
10			and once the counter drops out of considerable bounds, take
11			appropriate action.

13	What:		/sys/class/power/ds2760-battery.*/charge_full
14	Date:		May 2010
15	KernelVersion:	2.6.35
16	Contact:	Daniel Mack <daniel@caiaq.de>
17	Description:
18			This file is writeable and can be used to set the assumed
19			battery 'full level'. As batteries age, this value has to be
20			amended over time.

22	What:		/sys/class/power_supply/max14577-charger/device/fast_charge_timer
23	Date:		October 2014
24	KernelVersion:	3.18.0
25	Contact:	Krzysztof Kozlowski <k.kozlowski@samsung.com>
26	Description:
27			This entry shows and sets the maximum time the max14577
28			charger operates in fast-charge mode. When the timer expires
29			the device will terminate fast-charge mode (charging current
30			will drop to 0 A) and will trigger interrupt.
31	
32			Valid values:
33			- 5, 6 or 7 (hours),
34			- 0: disabled.

40	Description:
41			This entry shows and sets the maximum time the max77693
42			charger operates in fast-charge mode. When the timer expires
43			the device will terminate fast-charge mode (charging current
44			will drop to 0 A) and will trigger interrupt.
45	
46			Valid values:
47			- 4 - 16 (hours), step by 2 (rounded down)
48			- 0: disabled.

51	Date:		January 2015
52	KernelVersion:	3.19.0
53	Contact:	Krzysztof Kozlowski <k.kozlowski@samsung.com>
54	Description:
55			This entry shows and sets the charging current threshold for
56			entering top-off charging mode. When charging current in fast
57			charge mode drops below this value, the charger will trigger
58			interrupt and start top-off charging mode.
59	
60			Valid values:
61			- 100000 - 200000 (microamps), step by 25000 (rounded down)
62			- 200000 - 350000 (microamps), step by 50000 (rounded down)
63			- 0: disabled.

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

79	Date:		October 2015
80	KernelVersion:	4.4.0
81	Contact:	Andreas Dannenberg <dannenberg@ti.com>
82	Description:
83			This entry configures the overvoltage protection feature of bq24257-
84			type charger devices. This feature protects the device and other
85			components against damage from overvoltage on the input supply. See
86			device datasheet for details.
87	
88			Valid values:
89			- 6000000, 6500000, 7000000, 8000000, 9000000, 9500000, 10000000,

92	What:		/sys/class/power_supply/bq24257-charger/in_dpm_voltage
93	Date:		October 2015
94	KernelVersion:	4.4.0
95	Contact:	Andreas Dannenberg <dannenberg@ti.com>
96	Description:
97			This entry configures the input dynamic power path management voltage of
98			bq24257-type charger devices. Once the supply drops to the configured
99			voltage, the input current limit is reduced down to prevent the further
100			drop of the supply. When the IC enters this mode, the charge current is
101			lower than the set value. See device datasheet for details.
102	
103			Valid values:
104			- 4200000, 4280000, 4360000, 4440000, 4520000, 4600000, 4680000,
105			  4760000 (all uV)

107	What:		/sys/class/power_supply/bq24257-charger/high_impedance_enable
108	Date:		October 2015
109	KernelVersion:	4.4.0
110	Contact:	Andreas Dannenberg <dannenberg@ti.com>
111	Description:
112			This entry allows enabling the high-impedance mode of bq24257-type
113			charger devices. If enabled, it places the charger IC into low power
114			standby mode with the switch mode controller disabled. When disabled,
115			the charger operates normally. See device datasheet for details.
116	
117			Valid values:
118			- 1: enabled
119			- 0: disabled
120	
121	What:		/sys/class/power_supply/bq24257-charger/sysoff_enable
122	Date:		October 2015
123	KernelVersion:	4.4.0
124	Contact:	Andreas Dannenberg <dannenberg@ti.com>
125	Description:
126			This entry allows enabling the sysoff mode of bq24257-type charger
127			devices. If enabled and the input is removed, the internal battery FET
128			is turned off in order to reduce the leakage from the BAT pin to less
129			than 1uA. Note that on some devices/systems this disconnects the battery
130			from the system. See device datasheet for details.
131	
132			Valid values:
133			- 1: enabled
134			- 0: disabled
