Description

Intersil ISL68137 is a digital output 7-phase configurable PWM controller with an AVSBus interface.

Usage Notes

This driver does not probe for PMBus devices. You will have to instantiate devices explicitly.

The ISL68137 AVS operation mode must be enabled/disabled at runtime.

Beyond the normal sysfs pmbus attributes, the driver exposes a control attribute.

Additional Sysfs attributes
