Subject: [PATCH 06/11] OMAP2420: clock: add sdrc_ick
Date: Tue, 15 Feb 2011 23:52:50 -0700	[thread overview]
Message-ID: <20110216065248.22089.45836.stgit@twilight.localdomain> (raw)
In-Reply-To: <20110216065030.22089.61217.stgit@twilight.localdomain>

Add sdrc_ick to the OMAP2420 clock data so the clock code can control
the CM_AUTOIDLE bit associated with this clock.
