  11. Description
  12. -----------
  13. This driver supports hardware monitoring for Analog Devices LTC2991 Octal I2C
  14. Voltage, Current and Temperature Monitor.
  15. The LTC2991 is used to monitor system temperatures, voltages and currents.
  16. Through the I2C serial interface, the eight monitors can individually measure
  17. supply voltages and can be paired for differential measurements of current sense
  18. resistors or temperature sensing transistors. Additional measurements include
  19. internal temperatureand internal VCC.
  20. sysfs-Interface
