| Description | |
| ----------- | |
| The LTC4151 is a High Voltage I2C Current and Voltage Monitor. | |
| Usage Notes | |
| ----------- | |
| This driver does not probe for LTC4151 devices, since there is no register | |
| which can be safely used to identify the chip. You will have to instantiate | |
| the devices explicitly. | |
| Example: the following will load the driver for an LTC4151 at address 0x6f | |
| on I2C bus #0: | |
| # modprobe ltc4151 | |
| # echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device | |

| Voltage readings provided by this driver are reported as obtained from the ADIN | |
| and VIN registers. | |
| Current reading provided by this driver is reported as obtained from the Current | |
| Sense register. The reported value assumes that a 1 mOhm sense resistor is | |
| installed. | |
| in1_input VDIN voltage (mV) | |
| in2_input ADIN voltage (mV) | |
| curr1_input SENSE current (mA) |
