| 13 | Description |
| 14 | ----------- |
| 15 | |
| 16 | IR35221 is a Digital DC-DC Multiphase Converter |
| 17 | |
| 18 | |
| 19 | Usage Notes |
| 20 | ----------- |
| 21 | |
| 22 | This driver does not probe for PMBus devices. You will have to instantiate |
| 23 | devices explicitly. |
| 24 | |
| 25 | Example: the following commands will load the driver for an IR35221 |
| 26 | at address 0x70 on I2C bus #4: |
| 27 | |
| 28 | # modprobe ir35221 |
| 29 | # echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device |
