19Usage Notes
20-----------
21
22This driver does not probe for PMBus devices. You will have to instantiate
23devices explicitly.
24
25Example: the following commands will load the driver for an IR35221
26at address 0x70 on I2C bus #4:
27
28# modprobe ir35221
29# echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
