Subject: [PATCH 26/40] ARM i.MX3: Make ccm base address a variable
Date: Tue, 10 Apr 2012 15:45:39 +0200	[thread overview]
Message-ID: <1334065553-7565-27-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1334065553-7565-1-git-send-email-s.hauer@pengutronix.de>

Instead of having a cpu_is_* in each ccm register access it
is mor efficient to make it a variable.
