| 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 |
