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
