Subject: [PATCH v6 08/17] mtd: nand: omap: Copy platform data parameters to omap_nand_info data
Date: Thu, 7 Apr 2016 13:08:26 +0300	[thread overview]
Message-ID: <1460023715-19332-9-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1460023715-19332-1-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.
