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
