  22 Usage Notes
  23 -----------
  24
  25 This driver does not probe for PMBus devices. You will have to instantiate
  26 devices explicitly.
  27
  28 Example: the following commands will load the driver for an IR35221
  29 at address 0x70 on I2C bus #4::
  30
  31         # modprobe ir35221
  32         # echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
