From 4af33f1726b03997f70180466769cf28ddcaef85 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 18 Apr 2011 09:53:54 -0700 Subject: hwmon: (max16064) Add driver documentation MAX16064 has its own driver, thus should have its own documentation instead of being mentioned in the generic PMBus driver documentation.
