| 22 | Description |
| 23 | ----------- |
| 24 | |
| 25 | Intersil ISL68137 is a digital output 7-phase configurable PWM |
| 26 | controller with an AVSBus interface. |
| 27 | |
| 28 | Usage Notes |
| 29 | ----------- |
| 30 | |
| 31 | This driver does not probe for PMBus devices. You will have to instantiate |
| 32 | devices explicitly. |
| 33 | |
| 34 | The ISL68137 AVS operation mode must be enabled/disabled at runtime. |
| 35 | |
| 36 | Beyond the normal sysfs pmbus attributes, the driver exposes a control attribute. |
