+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.
+
