- Kernel driver ir35221
- =====================
- Supported chips:
- * Infineon IR35221
- Prefix: 'ir35221'
- Addresses scanned: -
- Datasheet: Datasheet is not publicly available.
- Author: Samuel Mendoza-Jonas <[email protected]>
- 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
