2015-12-08mtd: nand: embed an mtd_info structure into nand_chipBoris BREZILLON
Currently all NAND controller drivers are providing both the mtd_info and nand_chip struct and then let the NAND subsystem to initialize a few things before registering the mtd instance to the MTD layer. Embed an mtd_info field into nand_chip to add some consistency to all NAND controller drivers. This change will also help factorizing boilerplate code copied in all NAND drivers.

2015-12-04mtd: nand: r852: Remove unnecessary synchronize_irq() before free_irq()Lars-Peter Clausen
Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way), before any state associated with the IRQ is freed.

MTD allows compile-time configuration of the possible CFI geometry settings that are allowed by the kernel, but that includes a couple of invalid configurations, where no bank width or no interleave setting is allowed. These are then caught with a compile-time warning: include/linux/mtd/cfi.h:76:2: warning: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. include/linux/mtd/map.h:145:2: warning: #warning "No CONFIG_MTD_MAP_BANK_WIDTH_xx selected.

2015-11-19mtd: m25p80: fix module autoloading for "jedec, spi-nor" and "spi-nor"Brian Norris
Commit 43163022927b ("mtd: m25p80: allow arbitrary OF matching for "jedec,spi-nor"") moved the "jedec,spi-nor" handling from the spi_device_id table to the of_match_table, to better handle matching complex device tree compatible strings. With that patch, device tree support works as expected when m25p80.c is built into the kernel. However, that commit ignored the fact that: (1) (non-DT) platform devices might want to use the "spi-nor" string for matching with this driver, rather than picking an arbitrary one like "m25p80" (2) the core SPI uevent/modalias code doesn't yet support kernel module autoloading via of_match_table strings; so for DT-based devices, it will only report (part of) the first compatible string used Problem (1) has been reported previously, and I forgot to patch it up afterward. Problem (2) was noticed recently here: http://lists.infradead.org/pipermail/linux-mtd/2015-October/062369.html https://lkml.org/lkml/2015/11/12/574 Specifically, this patch fixes m25p80.ko module autoloading for cases like this: flash@xxx { compatible = "jedec,spi-nor"; ... }; because modalias of "spi:spi-nor" (the only module loading info provided by the SPI core for this device) will now be listed as an alias in m25p80.ko. Notably, it does *not* help cases like this: flash@xxx { compatible = "vendor,shiny-new-device", "jedec,spi-nor"; ... }; unless we also list "shiny-new-device" in m25p_ids[].

2015-11-16mtd: pxa3xx_nand: Increase the initial chunk sizeEzequiel García
The chunk size represents the size of the data chunks, which is used by the controllers that allow to split transfered data. However, the initial chunk size is used in a non-splitted way, during device identification. Therefore, it must be large enough for all the NAND commands issued during device identification. This includes NAND_CMD_PARAM which was recently changed to transfer up to 2048 bytes (for the redundant parameter pages). Thus, the initial chunk size should be 2048 as well. On Armada 370/XP platforms (NFCv2) booted without the keep-config devicetree property, this commit fixes a timeout on the NAND_CMD_PARAM command: [..] pxa3xx-nand f10d0000.nand: This platform can't do DMA on this device pxa3xx-nand f10d0000.nand: Wait time out!!! nand: device found, Manufacturer ID: 0x2c, Chip ID: 0x38 nand: Micron MT29F8G08ABABAWP nand: 1024 MiB, SLC, erase size: 512 KiB, page size: 4096, OOB size: 224 Signed-off-by: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> Acked-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2015-11-16mtd: nand: fix shutdown/reboot for multi-chip systemsBrian Norris
If multiple NAND chips are registered to the same controller, then when rebooting the system, the first one will grab the controller lock, while the second will wait forever for the first one to release it. i.e., a classic deadlock. This problem was solved for a similar case (suspend/resume) back in commit 6b0d9a841249 ("mtd: nand: fix multi-chip suspend problem"), and the shutdown state really isn't much different for us, so rather than adding a new special case to nand_get_device(), we can just overload the FL_PM_SUSPENDED state. Now, multiple chips can "get" the same controller lock (preventing further I/O), while we still allow other chips to pass through nand_shutdown().
