Subject: [PATCH v3 24/33] mtd: rawnand: txx9ndfmc: convert driver to nand_scan()
Date: Fri, 20 Jul 2018 01:00:17 +0200 [thread overview]
Message-ID: <20180719230026.8741-25-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20180719230026.8741-1-miquel.raynal@bootlin.com>
Two helpers have been added to the core to make ECC-related
configuration between the detection phase and the final NAND scan. Use
these hooks and convert the driver to just use nand_scan() instead of
both nand_scan_ident() and nand_scan_tail().
