 55Usage Notes
 56-----------
 57
 58This driver does not probe for PMBus devices. You will have
 59to instantiate devices explicitly.
 60
 61Example: the following commands will load the driver for an PXE1610
 62at address 0x70 on I2C bus #4::
 63
 64    # modprobe pxe1610
 65    # echo pxe1610 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
 66
 67It can also be instantiated by declaring in device tree
