[PATCH] OMAP4: DMTIMER: enable autoidle mode

From: Ambresh K
Date: Wed Jun 15 2011 - 17:12:41 EST


From: Ambresh K <ambresh@xxxxxx>

Currently autoidle is only enabled for OMAP2/3; by enabling autoidle,
the automatic L4 clock gating strategy is applied based on L4 activity,
otherwise L4 clock to module will be a free running.
