 30Description
 31-----------
 32
 33[From datasheets] The MAX16065/MAX16066 flash-configurable system managers
 34monitor and sequence multiple system voltages. The MAX16065/MAX16066 can also
 35accurately monitor (+/-2.5%) one current channel using a dedicated high-side
 36current-sense amplifier. The MAX16065 manages up to twelve system voltages
 37simultaneously, and the MAX16066 manages up to eight supply voltages.
 38
 39The MAX16067 flash-configurable system manager monitors and sequences multiple
 40system voltages. The MAX16067 manages up to six system voltages simultaneously.
 41
 42The MAX16068 flash-configurable system manager monitors and manages up to six
 43system voltages simultaneously.
 44
 45The MAX16070/MAX16071 flash-configurable system monitors supervise multiple
 46system voltages. The MAX16070/MAX16071 can also accurately monitor (+/-2.5%)
 47one current channel using a dedicated high-side current-sense amplifier. The
 48MAX16070 monitors up to twelve system voltages simultaneously, and the MAX16071
 49monitors up to eight supply voltages.
 50
 51Each monitored channel has its own low and high critical limits. MAX16065,
 52MAX16066, MAX16070, and MAX16071 support an additional limit which is
 53configurable as either low or high secondary limit. MAX16065, MAX16066,
 54MAX16070, and MAX16071 also support supply current monitoring.

 57Usage Notes
 58-----------
 59
 60This driver does not probe for devices, since there is no register which
 61can be safely used to identify the chip. You will have to instantiate
 62the devices explicitly. Please see Documentation/i2c/instantiating-devices for
 63details.
 64
 65WARNING: Do not access chip registers using the i2cdump command, and do not use
 66any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
 67supported by this driver interpret any access to a command register (including
 68read commands) as request to execute the command in question. This may result in
 69power loss, board resets, and/or Flash corruption. Worst case, your board may
 70turn into a brick.
