  19Description
  20-----------
  21
  22The LTC4151 is a High Voltage I2C Current and Voltage Monitor.

  25Usage Notes
  26-----------
  27
  28This driver does not probe for LTC4151 devices, since there is no register
  29which can be safely used to identify the chip. You will have to instantiate
  30the devices explicitly.
  31
  32Example: the following will load the driver for an LTC4151 at address 0x6f
  33on I2C bus #0::
  34
  35        # modprobe ltc4151
  36        # echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device

  42Voltage readings provided by this driver are reported as obtained from the ADIN
  43and VIN registers.
  44
  45Current reading provided by this driver is reported as obtained from the Current
  46Sense register. The reported value assumes that a 1 mOhm sense resistor is
  47installed.
