Description

IR35221 is a Digital DC-DC Multiphase Converter

Usage Notes

This driver does not probe for PMBus devices. You will have to instantiatedevices explicitly.

Example: the following commands will load the driver for an IR35221at address 0x70 on I2C bus #4:

# modprobe ir35221# echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
