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.
