mtd: nand: move raw NAND related code to the raw/ subdir

2018-02-16T09:09:34+00:00

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

mtd: nand: Get rid of comments giving the file path inside the file itself

2018-02-16T09:08:27+00:00

Some files add a comment giving the path of the file inside the Linux tree, which is pretty useless since the reader had to find the file to open it. Getting rid of these comments will also allow us to easily move these files around when needed. Signed-off-by: Boris Brezillon

mtd: nand: gpio: Fix ALE gpio configuration

mtd: nand: gpio: Convert to use GPIO descriptors

2017-10-07T09:27:48+00:00

There is exactly one board in the kernel that defines platform data for the GPIO NAND driver. Use the feature to provide a lookup table for the GPIOs in the board file so we can convert the driver as a whole to just use GPIO descriptors. After this we can cut the use of and use the GPIO descriptor management from alone to grab and use the GPIOs used in the driver. I also created a local struct device *dev in the probe() function because I was getting annoyed with all the &pdev->dev dereferencing.

mtd: nand: Rename nand.h into rawnand.h

2017-08-13T08:11:49+00:00

We are planning to share more code between different NAND based devices (SPI NAND, OneNAND and raw NANDs), but before doing that we need to move the existing include/linux/mtd/nand.h file into include/linux/mtd/rawnand.h so we can later create a nand.h header containing all common structure and function prototypes.

mtd: nand: gpio: make nCE GPIO optional

2017-03-16T09:34:27+00:00

On some hardware, the nCE signal is wired to the ChipSelect associated to bus address of the NAND, so it is automatically driven during the memory access and it is not managed by a GPIO. Signed-off-by: Christophe Leroy Reviewed-by: Marek Vasut Signed-off-by: Boris Brezillon

mtd: nand: gpio: return error code of nand_scan() on error

2016-11-07T13:48:43+00:00

The nand_scan() returns an appropriate error value when it fails. Use it instead of the fixed error code -ENXIO. Signed-off-by: Masahiro Yamada Reviewed-by: Marek Vasut Signed-off-by: Boris Brezillon

mtd: nand: gpio: set ECC algorithm explicitly

This is part of process deprecating NAND_ECC_SOFT_BCH (and switching to enum nand_ecc_algo). Signed-off-by: Rafał Miłecki Signed-off-by: Boris Brezillon

mtd: nand: remove useless mtd->priv = chip assignments

2015-12-18T21:21:40+00:00

mtd_to_nand() now uses the container_of() approach to transform an mtd_info pointer into a nand_chip one. Drop useless mtd->priv assignments from NAND controller drivers. Signed-off-by: Boris Brezillon Signed-off-by: Brian Norris

mtd: nand: gpio: use the mtd instance embedded in struct nand_chip
