Subject: [U-Boot] [PATCH 2/2] Blackfin: convert plat-nand code to GPIO framework
Date: Mon, 5 Jul 2010 04:55:05 -0400 [thread overview]
Message-ID: <1278320105-29086-2-git-send-email-vapier@gentoo.org> (raw)
In-Reply-To: <1278320105-29086-1-git-send-email-vapier@gentoo.org>
Use the new GPIO framework code in both the Blackfin arch and the
nand_plat driver to simplify things greatly.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>

note: i can run this through the Blackfin tree if you want
