Description
|
|
-----------
|
|
|
|
IR35221 is a Digital DC-DC Multiphase Converter
|
|
|
|
|
|
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 IR35221
|
|
at address 0x70 on I2C bus #4::
|
|
|
|
# modprobe ir35221
|
|
# echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
