2018-02-16mtd: nand: move raw NAND related code to the raw/ subdirBoris Brezillon1-233/+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>
2018-02-16mtd: nand: Get rid of comments giving the file path inside the file itselfBoris Brezillon1-2/+0
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 <boris.brezillon@bootlin.com>

2017-08-23mtd: nand: sharpsl: Register partitions using the parsersAndrea Adami1-1/+1
With the introduction of sharpslpart partition parser we can now read the offsets from NAND: we specify the list of the parsers as platform data, with cmdlinepart and ofpart parsers first allowing to override the part. table written in NAND. This is done in the board files using this driver. Use now these parsers. Signed-off-by: Andrea Adami <andrea.adami@gmail.com> Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
2017-08-13mtd: nand: Rename nand.h into rawnand.hBoris Brezillon1-1/+1
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.

2013-08-05mtd: nand: sharpsl: remove unnecessary platform_set_drvdata()Jingoo Han1-3/+0
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

2012-03-27mtd: flash drivers set ecc strengthMike Dunn1-0/+1
Flash device drivers initialize 'ecc_strength' in struct mtd_info, which is the maximum number of bit errors that can be corrected in one writesize region. Drivers using the nand interface intitialize 'strength' in struct nand_ecc_ctrl, which is the maximum number of bit errors that can be corrected in one ecc step. Nand infrastructure code translates this to 'ecc_strength'. Also for nand drivers, the nand infrastructure code sets ecc.strength for ecc modes NAND_ECC_SOFT, NAND_ECC_SOFT_BCH, and NAND_ECC_NONE. It is set in the driver for all other modes.

2012-03-27mtd: do not use plain 0 as NULLArtem Bityutskiy1-2/+2
The first 3 arguments of 'mtd_device_parse_register()' are pointers, but many callers pass '0' instead of 'NULL'. Fix this globally.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
