+Description
+-----------
+
+[From datasheets] The MAX16065/MAX16066 flash-configurable system managers
+monitor and sequence multiple system voltages. The MAX16065/MAX16066 can also
+accurately monitor (+/-2.5%) one current channel using a dedicated high-side
+current-sense amplifier. The MAX16065 manages up to twelve system voltages
+simultaneously, and the MAX16066 manages up to eight supply voltages.
+
+The MAX16067 flash-configurable system manager monitors and sequences multiple
+system voltages. The MAX16067 manages up to six system voltages simultaneously.
+
+The MAX16068 flash-configurable system manager monitors and manages up to six
+system voltages simultaneously.
+
+The MAX16070/MAX16071 flash-configurable system monitors supervise multiple
+system voltages. The MAX16070/MAX16071 can also accurately monitor (+/-2.5%)
+one current channel using a dedicated high-side current-sense amplifier. The
+MAX16070 monitors up to twelve system voltages simultaneously, and the MAX16071
+monitors up to eight supply voltages.
+
+Each monitored channel has its own low and high critical limits. MAX16065,
+MAX16066, MAX16070, and MAX16071 support an additional limit which is
+configurable as either low or high secondary limit. MAX16065, MAX16066,
+MAX16070, and MAX16071 also support supply current monitoring.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for devices, since there is no register which
+can be safely used to identify the chip. You will have to instantiate
+the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
+details.
+
+WARNING: Do not access chip registers using the i2cdump command, and do not use
+any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
+supported by this driver interpret any access to a command register (including
+read commands) as request to execute the command in question. This may result in
+power loss, board resets, and/or Flash corruption. Worst case, your board may
+turn into a brick.
