21Description
22-----------
23
24This driver supports hardware monitoring for Analog Devices LTC2991 Octal I2C
25Voltage, Current and Temperature Monitor.
26
27The LTC2991 is used to monitor system temperatures, voltages and currents.
28Through the I2C serial interface, the eight monitors can individually measure
29supply voltages and can be paired for differential measurements of current sense
30resistors or temperature sensing transistors. Additional measurements include
31internal temperatureand internal VCC.
