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 37 38 39Sysfs entries 40------------- 41 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. 48 49======================= ================== 50in1_input VDIN voltage (mV) 51 52in2_input ADIN voltage (mV) 53 54curr1_input SENSE current (mA) 55======================= ==================
