| 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. | |
| 37 | ||
| 38 | Additional Sysfs attributes | |
