Subject: [PATCH 1/4] ARM i.MX5: move pll setup defines to header file
Date: Wed, 28 Nov 2012 10:59:17 +0100	[thread overview]
Message-ID: <1354096760-14409-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1354096760-14409-1-git-send-email-s.hauer@pengutronix.de>

The pll setup function is exported, so it makes sense to export
the convenience wrappers for specific frequencies aswell.
