[PATCH v3 06/33] mtd: rawnand: fsl_ifc: convert driver to nand_scan()

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(). Signed-off-by: Miquel Raynal ---

[PATCH v3 23/33] mtd: rawnand: txx9ndfmc: rename nand controller internal structure

As already done in the core, calling a struct nand_controller 'hw_control' is misleading. Use the same name as in nand_base.c: 'controller'. Signed-off-by: Miquel Raynal --- drivers/mtd/nand/raw/txx9ndfmc.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git
