Subject: [PATCH] OMAP4: DMTIMER: enable autoidle mode
Date: Wed, 15 Jun 2011 14:12:35 -0700	[thread overview]
Message-ID: <1308172355-1694-1-git-send-email-ambresh@ti.com> (raw)

From: Ambresh K <ambresh@ti.com>

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.
