Subject: [PATCH 01/11] Separate framebuffer platformdata and the videomode
Date: Fri, 19 Nov 2010 13:50:53 +0100	[thread overview]
Message-ID: <1290171063-28870-2-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1290171063-28870-1-git-send-email-jbe@pengutronix.de>

This patch separates the imx platformdata and its videomode in two structures,
in order to support more than one defined videomode in the boardfile. This
is intended to support runtime videomode selection later on. It also uses
now the same videomode setup style than the imx-fpu based systems (like the
i.MX35).
