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
