[PATCH 2/4] pwm: kona: Fix incorrect enable after channel polarity change

From: Scott Branden
Date: Fri Nov 14 2014 - 13:31:50 EST


From: Arun Ramamurthy <arunrama@xxxxxxxxxxxx>

The pwm core code requires a separate call for enabling the channel
and hence the driver does not need to set pwm_trigger after a
polarity change
