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: 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: import nand_hw_control_init()

2016-09-23T07:35:16+00:00

The code to initialize a struct nand_hw_control is duplicated across several drivers. Factorize it using an inline function. Signed-off-by: Marc Gonzalez Signed-off-by: Boris Brezillon

mtd: nand: make use of nand_set/get_controller_data() helpers

2016-01-07T18:23:41+00:00

New helpers have been added to avoid directly accessing chip->field. Use them where appropriate. Signed-off-by: Boris Brezillon [Brian: fixed a few rebase conflicts] Signed-off-by: Brian Norris

mtd: nand: fix for drop unnecessary partition parser data

2016-01-05T23:57:59+00:00

From Stephen: Hi Brian, After merging the l2-mtd tree, today's linux-next build (powerpc ppc44x_defconfig) failed like this: drivers/mtd/nand/ndfc.c: In function 'ndfc_chip_init': drivers/mtd/nand/ndfc.c:177:2: error: 'ppdata' undeclared (first use in this function) ppdata.of_node = flash_np; ^ Caused by commit a61ae81a1907 ("mtd: nand: drop unnecessary partition parser data") The flash node is already correctly assigned using the new helper (nand_set_flash_node()) so the correct fix is indeed to simply drop this line.

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: ndfc: use the mtd instance embedded in struct nand_chip

2015-12-18T18:54:41+00:00

struct nand_chip now embeds an mtd device. Make use of this mtd instance. Signed-off-by: Boris Brezillon Signed-off-by: Brian Norris

mtd: nand: make use of mtd_to_nand() in NAND drivers

2015-12-08T20:24:36+00:00

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 Signed-off-by: Brian Norris

mtd: nand: drop unnecessary partition parser data

2015-11-11T21:58:45+00:00

All of these drivers set up a parser data struct just to communicate DT partition data. This field has been deprecated and is instead supported by telling nand_scan_ident() about the 'flash_node'. This patch: * sets chip->flash_node for those drivers that didn't already (but used OF partitioning) * drops the parser data * switches to the simpler mtd_device_register() where possible, now that we've eliminated one of the auxiliary parameters Now that we've assigned chip->flash_node for these drivers, we can probably rely on nand_dt_init() to do more of the DT parsing for us, but for now, I don't want to fiddle with each of these drivers. The parsing is done in duplicate for now on some drivers. I don't think this should break things. (Famous last words.)

mtd: nand: ndfc: show parent device in sysfs

2015-10-13T19:56:39+00:00

Fix a bug where parent device symlinks aren't shown in sysfs. While at it, make use of the default owner set by mtdcore. Signed-off-by: Frans Klaver Signed-off-by: Brian Norris
