Subject: [PATCH v3 10/27] mtd: nand: omap: Copy platform data parameters to omap_nand_info data
Date: Fri, 18 Sep 2015 17:53:32 +0300	[thread overview]
Message-ID: <1442588029-13769-11-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1442588029-13769-1-git-send-email-rogerq@ti.com>

Copy all the platform data parameters to the driver's local data
structure 'omap_nand_info' and use it in the entire driver. This will
make it easer for device tree migration.
