2026-02-06mtd: spinand: fix NULL pointer dereference in spinand_support_vendor_ops()Md Sadre Alam
The spinand_support_vendor_ops() helper unconditionally dereferences info->vendor_ops. For chips that do not define vendor_ops, this pointer is NULL, leading to a kernel panic during probe: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008 Add a guard to return early when vendor_ops is NULL. This prevents the crash and allows SPI NAND devices without vendor-specific operations to be probed correctly.

2026-01-30mtd: spinand: Disable continuous read during probeDavid LaPorte
Macronix serial NAND devices with continuous read support do not clear the configuration register on soft reset and lack a hardware reset pin. When continuous read is interrupted (e.g., during reboot), the feature remains enabled at the device level. With continuous read enabled, the OOB area becomes inaccessible and all reads are instead directed to the main area. As a result, during partition allocation as part of MTD device registration, the first two bytes of the main area for the master block are read and indicate that the block is bad. This process repeats for every subsequent block for the partition. All reads and writes that reference the BBT find no good blocks and fail. The only paths for recovery from this state are triggering the continuous read feature by way of raw MTD reads or through a NAND device power drain. Disable continuous read explicitly during spinand probe to ensure quiescent feature state.

2026-01-29mtd: spinand: winbond: W35N octal DTR supportMiquel Raynal
Extend the support for the W35N chip family by supporting the ODTR bus interface. The chip is capable to run in this mode, which brings a significant performance improvement. 1S-8S-8S: # flash_speed /dev/mtd0 -c1 -d eraseblock write speed is 7529 KiB/s eraseblock read speed is 15058 KiB/s 8D-8D-8D: # flash_speed /dev/mtd0 -c1 -d eraseblock write speed is 9481 KiB/s eraseblock read speed is 23272 KiB/s This is +55% read speed and +26% write speed with the same hardware. Tests have been conducted with a TI AM62A7 using the Cadence quad SPI controller. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2026-01-29mtd: spinand: Add octal DTR supportMiquel Raynal
Create a new bus interface named ODTR for "octal DTR", which matches the following pattern: 8D-8D-8D. Add octal DTR support for all the existing core operations. Add a second set of templates for this bus interface. Give the possibility for drivers to register their read, write and update cache variants as well as their vendor specific operations. Check the SPI controller driver supports all the octal DTR commands that we might need before switching to the ODTR bus interface. Make the switch by calling ->configure_chip() with the ODTR parameter. Fallback in case this step fails. If someone ever attempts to suspend a chip in octal DTR mode, there are changes that it will loose its configuration at resume. Prevent any problem by explicitly switching back to SSDR while suspending. Note: there is a limitation in the current approach, page I/Os are not available as the dirmaps will be created for the ODTR bus interface if that option is supported and not switched back to SSDR during suspend. Switching them is possible but would be costly and would not bring anything as right after resuming we will switch again to ODTR. In case this capability is used for debug, developpers should mind to destroy and recreate suitable direct mappings. Finally, as a side effect, we increase the buffer for reading IDs to 6. No device at this point returns 6 bytes, but we support 5 bytes IDs, which means in octal DTR mode we have no other choice than reading an even number of bytes, hence 6.

2026-01-29mtd: spinand: Warn if using SSDR-only vendor commands in a non SSDR modeMiquel Raynal

2026-01-29mtd: spinand: Give the bus interface to the configuration helperMiquel Raynal
The chip configuration hook is the one responsible to actually switch the switch between bus interfaces. It is natural to give it the bus interface we expect with a new parameter. For now the only value we can give is SSDR, but this is subject to change in the future, so add a bit of extra logic in the implementations of this callback to make sure both the core and the chip driver are aligned on the request. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2026-01-29mtd: spinand: Propagate the bus interface across core helpersMiquel Raynal
For now all drivers provide SSDR variants only. When we add support for ODTR modes, there will be a need to differentiate the type of variant we target as well as the need to check if we support one or the other type of operations. Pass this parameter to lower level helpers, which for now is unused, in order to simplify the patch introducing ODTR support. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2026-01-29mtd: spinand: Add support for setting a bus interfaceMiquel Raynal
Create a bus interface enumeration, currently only containing the one we support: SSDR, for single SDR, so any operation whose command is sent over a single data line in SDR mode, ie. any operation matching 1S-XX-XX. The main spinand_device structure gets a new parameter to store this enumeration, for now unused. Of course it is set to SSDR during the SSDR templates initialization to further clarify the state we are in at the moment. This member is subject to be used to know in which bus configuration we and be updated by the core when we switch to faster mode(s). Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2026-01-29mtd: spinand: Gather all the bus interface steps in one single functionMiquel Raynal
Writing the quad enable bit in one helper and doing the chip configuration in another does not make much sense from a bus interface setup point of view. Instead, let's create a broader helper which is going to be in charge of all the bus configuration steps at once. This will specifically allow to transition to octal DDR mode, and even fallback to quad (if suppoorted) or single mode otherwise. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2026-01-29mtd: spinand: winbond: Configure the IO mode after the dummy cyclesMiquel Raynal
When we will change the bus interface, the action that actually performs the transition is the IO mode register write. This means after the IO mode register write, we should use the new bus interface. But the ->configure_chip() hook itself is not responsible of making this change official, it is the caller that must act according to the return value. Reorganize this helper to first configure the dummy cycles before possibly switching to another bus interface. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

2026-01-29mtd: spinand: List vendor specific operations and make sure they are supportedMiquel Raynal
It is probably safe to expect that all SPI controller drivers will ever support all the most basic SPI NAND operations, such as write enable, register reads, page program, block erases, etc. However, what about vendor specific operations? So far nobody complained about it, but as we are about to introduce octal DTR support, and as none of the SPI NAND instruction set is defined in any standard, we must remain careful about these extra operations. One way to make sure we do not blindly get ourselves in strange situations with vendor commands failing silently is to make the check once for all, while probing the chip. However at this stage we have no such list, so let's add the necessary infrastructure to allow: - registering vendor operations, - checking they are actually supported when appropriate.

2026-01-29mtd: spinand: winbond: Convert W35N specific operation to SPINAND_OP()Miquel Raynal
Winbond W35N* chips require a vendor specific operation to write their VCR register (a configuration register, typically used for tuning the number of dummy cycles and switching to a different bus interface). Instead of defining this op only in the function that needs it, hiding it from the core, make it a proper define like all other spi-mem operations, and implement the necessary spinand_fill_*_op() helper to make the SPINAND_OP() macro work. This way we can use it from any function without any extra handling outside of this helper when we will convert the core to support octal DDR busses.

2026-01-29mtd: spinand: Make use of the operation templates through SPINAND_OP()Miquel Raynal
Create a SPINAND_OP() macro to which we give the name of the operation we want. This macro retrieves the correct operation template based on the current bus interface (currently only single SDR, will soon be extended to octal DTR) and fills it with the usual parameters. This macro makes the transition from calling directly the low-level macros into using the (bus interface dependent) templates very smooth. Use it in all places that can be trivially converted. At this stage there is no functional change expected, until octal DTR support gets added.

2026-01-29mtd: spinand: Create an array of operation templatesMiquel Raynal
Currently, the SPI NAND core implementation directly calls macros to get the various operations in shape. These macros are specific to the bus interface, currently only supporting the single SDR interface (any command following the 1S-XX-XX pattern). Introducing support for other bus interfaces (such as octal DTR) would mean that every user of these macros should become aware of the current bus interface and act accordingly, picking up and adapting to the current configuration. This would add quite a bit of boilerplate, be repetitive as well as error prone in case we miss one occurrence. Instead, let's create a table with all SPI NAND memory operations that are currently supported. We initialize them with the same single SDR _OP macros as before. This opens the possibility for users of the individual macros to make use of these templates instead. This way, when we will add another bus interface, we can just switch to another set of templates and all users will magically fill in their spi_mem_op structures with the correct ops. The existing read, write and update cache variants are also moved in this template array, which is barely noticeable by callers as we also add a structure member pointing to it.

spi: Octal DTR support This series adds support for 8D-8D-8D in SPI NAND, which can already be leveraged without any SPI changes as controllers already have this support for some SPI NOR devices. Among the few spi-mem patches, they are needed for building the SPI NAND changes (especially the ODTR introduction at the end) and therefore an immutable tag will be needed for merging in the MTD tree (unless all the series goes through MTD directly ofc).

SPI NAND changes: - Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added. SPI NOR changes: - Fix SMPT parsing for S25FS-S flash family. They report variable dummy cycles for reads. This results in the default of 0 being used. This works for other Infineon chips, but not for the S25FS-S family. They need 8 dummy cycles. Add fixup hooks to specify that. Also add fixup hooks to fix incorrect map ID data in SFDP. - Add support for a bunch of Winbond flashes. Their block protection information is not discoverable, so they need to have an entry in the flash tables to describe that. - Some cleanups for Micron flash support. - Add support for Micron mt35xu01gbba. - Some SPI controllers like the Intel one on the PCI bus do not support the read CR opcode (0x35). Do not use the opcode if the controller does not support it.

2025-11-28mtd: rawnand: renesas: Handle devm_pm_runtime_enable() errorsHaotian Zhang
devm_pm_runtime_enable() can fail due to memory allocation failures. The current code ignores its return value and proceeds with pm_runtime_resume_and_get(), which may operate on incorrectly initialized runtime PM state. Check the return value of devm_pm_runtime_enable() and return the error code if it fails.

2025-11-27mtd: nand: realtek-ecc: Fix Kconfig dependenciesMiquel Raynal
The driver uses DMA but does not mark it as a prerequisite in Kconfig. As it is also defined with COMPILE_TEST, autobuilders complain about certain symbols not being available when linking on architectures without DMA support (?) like sh. Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202511071114.8WeW2GZK-lkp@intel.com Cc: Markus Stockhausen <markus.stockhausen@gmx.de> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2025-11-27mtd: rawnand: sunxi: #undef field_{get,prep}() before local definitionGeert Uytterhoeven
Prepare for the advent of globally available common field_get() and field_prep() macros by undefining the symbols before defining local variants. This prevents redefinition warnings from the C preprocessor when introducing the common macros later.

This adds support for ESMT F50L1G41LC, which appears to be an updated version of the already supported F50L1G41LB. Add esmt_8c SPI_NAND manufacturer to account for the newly used vendor ID with support for the ESMT F50L1G41LC chip.

2025-11-17mtd: rawnand: lpc32xx_slc: Convert to use devm_gpiod_get_optional()Haotian Zhang
The initial fix for a GPIO descriptor leak added manual gpiod_put() calls in the error path and remove function. This follow-up patch improves upon the fix by switching to the resource-managed devm_gpiod_get_optional() API.
