| 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 |
