Subject: [PATCH 2/8] memory: emif: setup LP settings on freq update
Date: Mon, 11 Mar 2013 10:35:59 +0530	[thread overview]
Message-ID: <1362978365-5593-3-git-send-email-lokeshvutla@ti.com> (raw)
In-Reply-To: <1362978365-5593-1-git-send-email-lokeshvutla@ti.com>

From: Ambresh K <ambresh@ti.com>

Program the power management shadow register on freq update
Else the concept of threshold frequencies dont really matter
as the system always uses the performance mode timing for LP
which is programmed in at init time.
