From: Rajendra Nayak <rnayak@xxxxxx> If a module's OCP slave port is programmed to be in smartidle, its also necessary that they have module level wakeup enabled. Update _sysc_enable in hwmod framework to do this. The thread "[PATCH 7/8] : Hwmod api changes" archived here: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg34212.html has additional technical information on the rationale of this patch.
