Subject: [PATCH 1/9] ARM omap: move uart access functions to a more generic place
Date: Mon, 4 Apr 2011 15:13:55 +0200 [thread overview]
Message-ID: <1301922843-12118-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1301922843-12118-1-git-send-email-s.hauer@pengutronix.de>
These functions can be used on omap4 aswell, so move them to
omap.c
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
