22Usage Notes
23-----------
24
25This driver does not probe for PMBus devices. You will have to instantiate
26devices explicitly.
27
28Example: the following commands will load the driver for an IR35221
29at address 0x70 on I2C bus #4::
30
31	# modprobe ir35221
32	# echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
