- 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 for
- details.
- Sysfs entries
- -------------
- in[0-11]_input Input voltage measurements.
- in12_input Voltage on CSP (Current Sense Positive) pin.
- Only if the chip supports current sensing and if
- current sensing is enabled.
- in[0-11]_min Low warning limit.
- Supported on MAX16065, MAX16066, MAX16070, and MAX16071
- only.
- in[0-11]_max High warning limit.
- Supported on MAX16065, MAX16066, MAX16070, and MAX16071

- (depending on chip configuration), but not both.
- in[0-11]_lcrit Low critical limit.
- in[0-11]_crit High critical limit.
- in[0-11]_alarm Input voltage alarm.
- curr1_input Current sense input; only if the chip supports current
- sensing and if current sensing is enabled.
- Displayed current assumes 0.001 Ohm current sense
- resistor.
- curr1_alarm Overcurrent alarm; only if the chip supports current
- sensing and if current sensing is enabled.
