0022 Usage Notes
0023 -----------
0024
0025 This driver does not probe for PMBus devices. You will have to instantiate
0026 devices explicitly.
0027
0028 Example: the following commands will load the driver for an IR35221
0029 at address 0x70 on I2C bus #4::
0030
0031 # modprobe ir35221
0032 # echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
