|
|
Usage Notes
|
|
-----------
|
|
|
|
This driver does not probe for PMBus devices. You will have to instantiate
|
|
devices explicitly.
|
|
|
|
Example: the following commands will load the driver for an LTC3815
|
|
at address 0x20 on I2C bus #1::
|
|
|
|
# modprobe ltc3815
|
|
# echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device
