OMAP: hwmod: Enable module wakeup if in smartidle
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@vger.kernel.org/msg34212.html
has additional technical information on the rationale of this patch.
