2018-02-16mtd: nand: move raw NAND related code to the raw/ subdirBoris Brezillon1-456/+0
As part of the process of sharing more code between different NAND based devices, we need to move all raw NAND related code to the raw/ subdirectory. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
2017-05-30mtd: nand: Make sure drivers not supporting SET/GET_FEATURES return -ENOTSUPPBoris Brezillon1-0/+2
A lot of drivers are providing their own ->cmdfunc(), and most of the time this implementation does not support all possible NAND operations. But since ->cmdfunc() cannot return an error code, the core has no way to know that the operation it requested is not supported. This is a problem we cannot address for all kind of operations with the current design, but we can prevent these silent failures for the GET/SET FEATURES operation by overloading the default ->onfi_{set,get}_features() methods with one returning -ENOTSUPP.

2016-01-07mtd: nand: make use of nand_set/get_controller_data() helpersBoris BREZILLON1-8/+8
New helpers have been added to avoid directly accessing chip->field. Use them where appropriate. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> [Brian: fixed a few rebase conflicts] Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2015-12-18mtd: nand: bcm47xx: use the mtd instance embedded in struct nand_chipBoris BREZILLON1-1/+1

2015-12-08mtd: nand: make use of mtd_to_nand() in NAND driversBoris BREZILLON1-8/+8
mtd_to_nand() was recently introduced to avoid direct accesses to the mtd->priv field. Update all NAND drivers to use it. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

This won't be used by NAND subsystem as we implement cmdfunc on our own, but will allow us to write a bit cleaner code. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

Pull MTD update from David Woodhouse: "Fairly unexciting MTD merge for 3.9: - misc clean-ups in the MTD command-line partitioning parser (cmdlinepart) - add flash locking support for STmicro chips serial flash chips, as well as for CFI command set 2 chips. - new driver for the ELM error correction HW module found in various TI chips, enable the OMAP NAND driver to use the ELM HW error correction - added number of new serial flash IDs - various fixes and improvements in the gpmi NAND driver - bcm47xx NAND driver improvements - make the mtdpart module actually removable" * tag 'for-linus-20130301' of git://git.infradead.org/linux-mtd: (45 commits) mtd: map: BUG() in non handled cases mtd: bcm47xxnflash: use pr_fmt for module prefix in messages mtd: davinci_nand: Use managed resources mtd: mtd_torturetest can cause stack overflows mtd: physmap_of: Convert device allocation to managed devm_kzalloc() mtd: at91: atmel_nand: for PMECC, add code to check the ONFI parameter ECC requirement. mtd: atmel_nand: make pmecc-cap, pmecc-sector-size in dts is optional. mtd: atmel_nand: avoid to report an error when lookup table offset is 0. mtd: bcm47xxsflash: adjust names of bus-specific functions mtd: bcm47xxpart: improve probing of nvram partition mtd: bcm47xxpart: add support for other erase sizes mtd: bcm47xxnflash: register this as normal driver mtd: bcm47xxnflash: fix message mtd: bcm47xxsflash: register this as normal driver mtd: bcm47xxsflash: write number of written bytes mtd: gpmi: add sanity check for the ECC mtd: gpmi: set the Golois Field bit for mx6q's BCH mtd: devices: elm: Removes <xx> literals in elm DT node mtd: gpmi: fix a dereferencing freed memory error mtd: fix the wrong timeo for panic_nand_wait() ...
