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
