From 4aa67e94d6b13905abcf3e95cb66ea7be9c2e8dd Mon Sep 17 00:00:00 2001
From: Nishanth Menon <nm@ti.com>
Date: Mon, 14 Feb 2011 21:14:17 +0530
Subject: [PATCH 11/12] OMAP3+: SR: enable/disable SR only on need
Since we already know the state of the autocomp enablement, we can
see if the requested state is different from the current state and
enable/disable SR only on the need basis.
