v6:
Fix reversed logic bug.
v5:
Drop extra parens
Drop extra parameter check
v4:
Use kstrtobool
Cleanup parens
Use rc instead of temporary int
Delete unnecessary coment
Add remove to driver structure
v3:
Added missing driver documentation
Cleaned up goto statements.
Add missing error check on pmbus_read_word_data
Transitioned to use SENSOR_DEVICE_ATTR_RW
Renamed enabled attribute to enable
Set up an attribute_group for the enable attribute and added to pmbus_info

+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
+---------------------------
+
+avs(0|1)_enable Controls the AVS state of each rail.

I trim out a bunch beneath this, so maybe that's causing corruption?
For instance, all the Google footers, etc, is cut out manually. If
that's an issue for the patch email hash, I can do that in the commit
log -- since it may include the commit message.
