Description
-----------
Intersil ISL68137 is a digital output 7-phase configurable PWM
controller with an AVSBus interface.
This driver supports the Renesas ISL68137 and all 2nd generation Renesas
digital multiphase voltage regulators (raa_dmpvr2). The ISL68137 is a digital
output 7-phase configurable PWM controller with an AVSBus interface. 2nd
generation devices are grouped into 4 distinct configurations: '1rail' for
single-rail devices, '2rail' for dual-rail devices, '3rail' for 3-rail devices,
and 'hv' for high voltage single-rail devices. Consult the individual datasheets
for more information.
Usage Notes

The ISL68137 AVS operation mode must be enabled/disabled at runtime.
Beyond the normal sysfs pmbus attributes, the driver exposes a control attribute.
Beyond the normal sysfs pmbus attributes, the driver exposes a control attribute
for the ISL68137.
For 2nd generation Renesas digital multiphase voltage regulators, only the
normal sysfs pmbus attributes are supported.
