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 LTC3815
26at address 0x20 on I2C bus #1:
27
28# modprobe ltc3815
29# echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device
