mtd: m25p80,spi-nor: Fix module aliases for m25p80

2014-10-21T20:46:03+00:00

m25p80's device ID table is now spi_nor_ids, defined in spi-nor. The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80.

mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id

2014-10-17T16:29:21+00:00

Drivers currently call spi_nor_match_id() and then spi_nor_scan(). This adds a dependency on struct spi_device_id which we want to avoid. Make spi_nor_scan() do it for them. Signed-off-by: Ben Hutchings Signed-off-by: Rafał Miłecki Signed-off-by: Brian Norris

mtd: nand: support ONFI timing mode retrieval for non-ONFI NANDs

2014-09-22T18:29:57+00:00

Add an onfi_timing_mode_default field to nand_chip and nand_flash_dev in order to support NAND timings definition for non-ONFI NAND. NAND that support better timings mode than the default one have to define a new entry in the nand_ids table. The default timing mode should be deduced from timings description from the datasheet and the ONFI specification (www.onfi.org/~/media/ONFI/specs/onfi_3_1_spec.pdf, chapter 4.15 "Timing Parameters"). You should choose the closest mode that fit the timings requirements of your NAND chip. Signed-off-by: Boris BREZILLON Signed-off-by: Brian Norris

mtd: nand: fix DocBook warnings on nand_sdr_timings doc

2014-08-19T18:55:38+00:00

Change the comment type (from /** to /*) to prevent DocBook from complaining about missing description for nand_sdr_timings fields. There is currently no need in documenting those fields because they are fully described in the ONFI specification (which is pointed out in the comment).

mtd: spi-nor: add support for flag status register on Micron chips

2014-07-12T02:10:35+00:00

Some new Micron flash chips require reading the flag status register to determine when operations have completed. Furthermore, chips with multi-die stacks of the 65nm 256Mb QSPI also require reading the status register before reading the flag status register. This patch adds support for the flag status register in the n25q512ax3 and n25q00 Micron QSPI flash chips. Signed-off-by: Graham Moore Signed-off-by: Brian Norris
