+* Harmonize 'smart fan' support.
+  The following drivers support pwm. The ones that support
+  automatic or smart fan support are identified.
+  We have a /proc standard for manual PWM support that allows
+  for /proc based applications like pwmconfig and fancontrol
+  in our package.
+  Without a /proc standard for smart fan support such applications
+  are much more difficult.
