- Description
- -----------
- Chips in this series are multi-phase step-down converters with one or two
- output channels and up to 8 phases per channel.
- 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 TPS53681 at address
- 0x60 on I2C bus #1::
- # modprobe tps53679
- # echo tps53681 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
- Sysfs attributes
