Subject: [PATCH 05/14] STM378x: Parameterize the max. possible GPIO number
Date: Mon, 13 Dec 2010 11:53:28 +0100 [thread overview]
Message-ID: <1292237617-7064-6-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1292237617-7064-1-git-send-email-jbe@pengutronix.de>
This is for easier integration of the i.MX28 architecture (to share the code
later on).
