| 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. |
