  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.
