Pull NAND changes from Boris Brezillon: """ This pull request contains only one notable change: * Addition of the MTK NAND controller driver And a bunch of specific NAND driver improvements/fixes. Here are the changes that are worth mentioning: * A few fixes/improvements for the xway NAND controller driver * A few fixes for the sunxi NAND controller driver * Support for DMA in the sunxi NAND driver * Support for the sunxi NAND controller IP embedded in A23/A33 SoCs * Addition for bitflips detection in erased pages to the brcmnand driver * Support for new brcmnand IPs * Update of the OMAP-GPMC binding to support DMA channel description """

mtd: nand: add ESMT manufacturer

2016-06-09T19:23:20Z

I got device with ESMT (Elite Semiconductor Memory Technology Inc) F59L1G81MA flash that was detected as: [ 0.852034] nand: device found, Manufacturer ID: 0xc8, Chip ID: 0xd1 [ 0.858402] nand: Unknown NAND 128MiB 3,3V 8-bit [ 0.863031] nand: 128MiB, SLC, page size: 2048, OOB size: 64 According to the F59L1G81MA datasheet (and Read Id documentation) C8h is a "Maker Code" which should mean ESMT. Add it to fix above "Unknown". Signed-off-by: Rafał Miłecki Signed-off-by: Boris Brezillon

mtd: spi-nor: stop passing around retlen

2016-06-02T00:22:52Z

Do not pass retlen to hardware driver read/write functions. Update it in spi-nor generic driver instead. Signed-off-by: Michal Suchanek Signed-off-by: Brian Norris Tested-by Cyrille Pitchen Acked-by: Michal Suchanek Tested-by: Michal Suchanek

mtd: spi-nor: change return value of read/write

2016-06-02T00:22:28Z

Change the return value of spi-nor device read and write methods to allow returning amount of data transferred and errors as read(2)/write(2) does. Also, start handling positive returns in spi_nor_read(), since we want to convert drivers to start returning the read-length both via *retlen and the return code. (We don't need to do the same transition process for spi_nor_write(), since ->write() didn't used to have a return code at all.)

mtd: spi-nor: support GigaDevice gd25lq64c

2016-05-10T22:44:18Z

Also note the GigaDevice JEDEC ID. No write-protect support yet, since this flash uses a different status register layout. Cc: Ezequiel Garcia Signed-off-by: Brian Norris Acked-by: Marek Vasut

Merge tag 'nand/for-4.7' of github.com:linux-nand/linux

2016-05-06T01:04:53Z

Updates from Boris Brezillon: This pull request contains the following infrastructure changes: * introduction of the ECC algo concept to extend the ECC mode one * replacement of the nand_ecclayout infrastructure by something more future-proof. * addition of an mtd-activity led trigger to replace the nand-activity one And a bunch of specific NAND driver improvements/fixes. Here are the changes that are worth mentioning: * rework of the OMAP GPMC and NAND drivers * prepare the sunxi NAND driver to receive DMA support * handle bitflips in erased pages on GPMI revisions that do not support this in hardware. * tag 'nand/for-4.7' of github.com:linux-nand/linux: (152 commits) mtd: brcmnand: respect ECC algorithm set by NAND subsystem gpmi-nand: Handle ECC Errors in erased pages Documentation: devicetree: deprecate "soft_bch" nand-ecc-mode value mtd: nand: add support for "nand-ecc-algo" DT property mtd: mtd: drop NAND_ECC_SOFT_BCH enum value mtd: drop support for NAND_ECC_SOFT_BCH as "soft_bch" mapping mtd: nand: read ECC algorithm from the new field mtd: nand: fsmc: validate ECC setup by checking algorithm directly mtd: nand: set ECC algorithm to Hamming on fallback staging: mt29f_spinand: set ECC algorithm explicitly CRIS v32: nand: set ECC algorithm explicitly mtd: nand: atmel: set ECC algorithm explicitly mtd: nand: davinci: set ECC algorithm explicitly mtd: nand: bf5xx: set ECC algorithm explicitly mtd: nand: omap2: Fix high memory dma prefetch transfer mtd: nand: omap2: Start dma request before enabling prefetch mtd: nandsim: add __init attribute mtd: nand: move of_get_nand_xxx() helpers into nand_base.c mtd: nand: sh_flctl: rely on generic DT parsing done in nand_scan_ident() mtd: nand: mxc: rely on generic DT parsing done in nand_scan_ident() ...

mtd: mtd: drop NAND_ECC_SOFT_BCH enum value

2016-05-05T21:55:13Z

This value should not be part of nand_ecc_modes_t as it specifies algorithm not a mode. We successfully managed to introduce new "algo" field which is respected now. Signed-off-by: Rafał Miłecki Signed-off-by: Boris Brezillon

mtd: kill the nand_ecclayout struct

2016-05-05T21:51:51Z

Now that all MTD drivers have moved to the mtd_ooblayout_ops model we can safely remove the struct nand_ecclayout definition, and all the remaining places where it was still used. Signed-off-by: Boris Brezillon

mtd: nand: kill the ecc->layout field

2016-05-05T21:51:50Z

Now that all NAND drivers have switched to mtd_ooblayout_ops, we can kill the ecc->layout field. Signed-off-by: Boris Brezillon

mtd: onenand: switch to mtd_ooblayout_ops

2016-05-05T21:51:49Z

Implementing the mtd_ooblayout_ops interface is the new way of exposing ECC/OOB layout to MTD users. Modify the onenand drivers to switch to this approach. Signed-off-by: Boris Brezillon
