Subject: [PATCH 01/10] mtd: nand: register nand flashes with nand specific function
Date: Mon,  4 Mar 2013 11:13:45 +0100	[thread overview]
Message-ID: <1362392034-1908-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1362392034-1908-1-git-send-email-s.hauer@pengutronix.de>

This allows us to have some NAND specific stuff during registration,
like for example adding NAND specific device parameters.
