50Description
51-----------
52
53[From datasheets] The MAX16065/MAX16066 flash-configurable system managers
54monitor and sequence multiple system voltages. The MAX16065/MAX16066 can also
55accurately monitor (+/-2.5%) one current channel using a dedicated high-side
56current-sense amplifier. The MAX16065 manages up to twelve system voltages
57simultaneously, and the MAX16066 manages up to eight supply voltages.
58
59The MAX16067 flash-configurable system manager monitors and sequences multiple
60system voltages. The MAX16067 manages up to six system voltages simultaneously.
61
62The MAX16068 flash-configurable system manager monitors and manages up to six
63system voltages simultaneously.
64
65The MAX16070/MAX16071 flash-configurable system monitors supervise multiple
66system voltages. The MAX16070/MAX16071 can also accurately monitor (+/-2.5%)
67one current channel using a dedicated high-side current-sense amplifier. The
68MAX16070 monitors up to twelve system voltages simultaneously, and the MAX16071
69monitors up to eight supply voltages.
70
71Each monitored channel has its own low and high critical limits. MAX16065,
72MAX16066, MAX16070, and MAX16071 support an additional limit which is
73configurable as either low or high secondary limit. MAX16065, MAX16066,
74MAX16070, and MAX16071 also support supply current monitoring.

77Usage Notes
78-----------
79
80This driver does not probe for devices, since there is no register which
81can be safely used to identify the chip. You will have to instantiate
82the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
83details.
84
85WARNING: Do not access chip registers using the i2cdump command, and do not use
86any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
87supported by this driver interpret any access to a command register (including
88read commands) as request to execute the command in question. This may result in
89power loss, board resets, and/or Flash corruption. Worst case, your board may
90turn into a brick.
