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