Add support for LTC2991 Octal I2C Voltage, Current, and Temperature Monitor. The LTC2991 is used to monitor system temperatures, voltages and currents. Through the I2C serial interface, the eight monitors can individually measure supply voltages and can be paired for differential measurements of current sense resistors or temperature sensing transistors. Additional measurements include internal temperature and internal VCC.

Description
|
|
-----------
|
|
|
|
This driver supports hardware monitoring for Analog Devices LTC2991 Octal I2C
|
|
Voltage, Current and Temperature Monitor.
|
|
|
|
The LTC2991 is used to monitor system temperatures, voltages and currents.
|
|
Through the I2C serial interface, the eight monitors can individually measure
|
|
supply voltages and can be paired for differential measurements of current sense
|
|
resistors or temperature sensing transistors. Additional measurements include
|
|
internal temperatureand internal VCC.
