  19 Usage Notes
  20 -----------
  21
  22 This driver does not probe for PMBus devices. You will have to instantiate
  23 devices explicitly.
  24
  25 Example: the following commands will load the driver for an IR35221
  26 at address 0x70 on I2C bus #4:
  27
  28 # modprobe ir35221
  29 # echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
