Raw NAND changes: * The major change in this MR will be the support for the Allwinner H616 NAND controller, which lead to numerous changes and cleanups in the driver. * Another notable change on this driver is the use of field_get()/field_prep(), but since the global support for this helpers is going to be merged in the same release as we start using these helpers, it implies undefining them in the first place to avoid warnings. Depending on the merging order (Yuri's bitmap branch or mtd/next), a temporary warning may arise. * Marvell drivers layout handling changes have also landed, they fix previous definitions and abuses that have been made previously, which implied to relax the ECC parameters validation in the core a bit. * The Cadence NAND controller driver gets NV-DDR interface support. SPI NAND changes: * Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added. Aside from these main changes, there is the usual load of fixes and API updates.

mtd: spinand: esmt: add support for F50L1G41LC

2025-11-17T10:53:08Z

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.

Correct most kernel-doc warnings in include/linux/mtd/spear_smi.h by adding a leading '@' to the description of struct members. Add a new description for the missing @np member.

* Raw NAND: - Add support for Loongson-2K1000 and Loongson-2K0500 NAND controllers, including extra features, such as chip select and 6-byte NAND ID reading support. - Drop the s3c2410 driver. * SPI NAND: - Important SPI NAND continuous read improvements and fixes. - Add support for FudanMicro FM25S01A. - Add support for continuous reads in Gigadevice vendor driver. * ECC: - Add support for the Realtek ECC engine. This PR comes with the usual amount of various miscellaneous fixes. Signed-off-by: Miquel Raynal

mtd: nand: move nand_check_erased_ecc_chunk() to nand/core

2025-09-18T08:32:00Z

The check function for bitflips in erased blocks will be needed by the Realtek ECC engine driver (which is currently under development). Right now it is located in raw/nand_base.c. While this is sufficient for the current usecases, there is no real dependency for an ECC engine on the raw nand library. Move the function over to a more generic place in core library.

mtd: nand: qpic-common: remove a bunch of unused defines

2025-08-28T12:23:20Z

A bunch of definitions in the 'nand-qpic-common.h' header became unused after the conversion of the 'qcom_nandc' and 'spi-qpic-snand' drivers to use the FIELD_PREP() macro, so remove those. No functional changes. Signed-off-by: Gabor Juhos Signed-off-by: Miquel Raynal

Pull mtd updates from Miquel Raynal: "MTD changes: - Apart from a binding conversion to yaml, only minor changes/small fixes have been merged. Raw NAND changes: - Minor fixes for various controller drivers like DMA mapping checks, better timing derivations or bitflip statistics. - some Hynix NAND flashes were not supporting read-retries, so don't even try to do it SPI NAND changes: - In order to support high-speed modes, certain chips need extra configuration like adding more dummy cycles. This is now possible, especially on Winbond chips. - Aside from that, Gigadevice gets support for a new chip (GD5F1GM9). SPI NOR changes: - A notable changes is the fix for exiting 4-byte addressing on Infineon SEMPER flashes. These flashes do not support the standard EX4B opcode (E9h), and use a vendor-specific opcode (B8h) instead. - There is also a fix for unlocking flashes that are write-protected at power-on. This was caused by using an uninitialized mtd_info in spi_nor_try_unlock_all()" * tag 'mtd/for-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: (26 commits) mtd: spinand: winbond: Add comment about the maximum frequency mtd: spinand: winbond: Enable high-speed modes on w35n0xjw mtd: spinand: winbond: Enable high-speed modes on w25n0xjw mtd: spinand: Add a ->configure_chip() hook mtd: spinand: Add a frequency field to all READ_FROM_CACHE variants mtd: spinand: Fix macro alignment spi: spi-mem: Take into account the actual maximum frequency spi: spi-mem: Use picoseconds for calculating the op durations mtd: rawnand: atmel: set pmecc data setup time mtd: spinand: propagate spinand_wait() errors from spinand_write_page() mtd: rawnand: fsmc: Add missing check after DMA map mtd: rawnand: rockchip: Add missing check after DMA map mtd: rawnand: hynix: don't try read-retry on SLC NANDs mtd: rawnand: atmel: Fix dma_mapping_error() address mtd: nand: brcmnand: fix mtd corrected bits stat mtd: rawnand: renesas: Add missing check after DMA map mtd: spinand: gigadevice: Add support for GD5F1GM9 chips mtd: nand: brcmnand: replace manual string choices with standard helpers mtd: map: Don't use "proxy" headers mtd: spi-nor: Fix spi_nor_try_unlock_all() ...
