| 60 | Description |
| 61 | ----------- |
| 62 | |
| 63 | Chips in this series are multi-phase step-down converters with one or two |
| 64 | output channels and up to 8 phases per channel. |
| 65 | |
| 66 | |
| 67 | Usage Notes |
| 68 | ----------- |
| 69 | |
| 70 | This driver does not probe for PMBus devices. You will have to instantiate |
| 71 | devices explicitly. |
| 72 | |
| 73 | Example: the following commands will load the driver for an TPS53681 at address |
| 74 | 0x60 on I2C bus #1:: |
| 75 | |
| 76 | # modprobe tps53679 |
| 77 | # echo tps53681 0x60 > /sys/bus/i2c/devices/i2c-1/new_device |
