| 16 | Description | |
| 17 | ----------- | |
| 18 | ||
| 19 | IR35221 is a Digital DC-DC Multiphase Converter | |
| 20 | ||
| 21 | ||
| 22 | Usage Notes | |
| 23 | ----------- | |
| 24 | ||
| 25 | This driver does not probe for PMBus devices. You will have to instantiate | |
| 26 | devices explicitly. | |
| 27 | ||
| 28 | Example: the following commands will load the driver for an IR35221 | |
| 1f234ff1 | 29 | at address 0x70 on I2C bus #4:: |
| 8991ebd9 | 30 | |
| 1f234ff1 MCC |
31 | # modprobe ir35221 |
| 32 | # echo ir35221 0x70 > /sys/bus/i2c/devices/i2c-4/new_device | |
