Pull mtd updates from Miquel Raynal: "MTD changes: - The atmel,dataflash binding has been converted to yaml and the physmap one constrained. Some logs are improved, error path are getting reworked a bit, few patches target the use of str_enabled_disabled(). Raw NAND changes: - i.MX8 and i.MX31 now have their own compatible, the Qcom driver got cleaned, the Broadcom driver got fixed. SPI NAND changes: - OTP support has been brought, and ESMT and Micron manufacturer drivers implement it. - Read retry, and Macronix manufacturer driver implement it. SPI NOR changes: - Adding support for few flashes. Few cleanup patches for the core driver, where we touched the headers inclusion list and we start using the scope based mutex cleanup helpers. There is also a bunch of minor improvements and fixes in drivers and bindings" * tag 'mtd/for-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: (34 commits) dt-bindings: mtd: atmel,dataflash: convert txt to yaml mtd: mchp48l640: Use str_enable_disable() in mchp48l640_write_prepare() mtd: rawnand: gpmi: Use str_enabled_disabled() in gpmi_nand_attach_chip() mtd: mtdpart: Do not supply NULL to printf() dt-bindings: mtd: gpmi-nand: Add compatible string for i.MX8 chips mtd: nand: Fix a kdoc comment mtd: spinand: Improve spinand_info macros style mtd: spi-nor: drop unused mtd: spi-nor: explicitly include mtd: spi-nor: explicitly include mtd: spi-nor: macronix: add support for mx66{l2, u1}g45g mtd: spi-nor: macronix: Add post_sfdp fixups for Quad Input Page Program mtd: Fix error handling in mtd_device_parse_register() error path mtd: capture device name setting failure when adding mtd mtd: Add check for devm_kcalloc() mtd: Replace kcalloc() with devm_kcalloc() dt-bindings: mtd: physmap: Ensure all properties are defined mtd: rawnand: brcmnand: fix PM resume warning dt-bindings: mtd: mxc-nand: Document fsl,imx31-nand mtd: spinand: macronix: Add support for read retry ...

* Raw NAND changes: i.MX8 and i.MX31 now have their own compatible, the Qcom driver got cleaned, the Broadcom driver got fixed. * SPI NAND changes: Two main features have been added: - OTP support has been brought, and ESMT and Micron manufacturer drivers implement it. - Read retry, and Macronix manufacturer driver implement it. There is as well a bunch of minor improvements and fixes in drivers and bindings.

dt-bindings: mtd: gpmi-nand: Add compatible string for i.MX8 chips

Add compatible string "fsl,imx8mp-gpmi-nand" and "fsl,imx8mq-gpmi-nand", which back compatible with i.MX7D. So set these fall back to "fsl,imx7d-gpmi-nand". Add compatible string "fsl,imx8qm-gpmi-nand" and "fsl,imx8dxl-gpmi-nand", which back compatible with i.MX8QXP. So set these fall back to "fsl,imx8qxp-gpmi-nand".

dt-bindings: mtd: cadence: document required clock-names

2025-02-14T18:25:43Z

The clock-names property is required because the driver requests the clock by name and not the index. Update the example to use &clk instead of &nf_clk for the clocks property to avoid confusion with the clock-names property "nf_clk".

* Raw NAND changes A new controller driver, from Nuvoton, has been merged. Bastien Curutchet has contributed a series improving the Davinci controller driver, both on the organization of the code, but also on the performance side. The binding has also been converted to yaml, received a new OOB layout and now supports on-die ECC engines. The Qualcomm controller driver has been deeply cleaned to extract some parts of the code into a shared file with the Qualcomm SPI memory controller. Aside from these main changes, the Cadence binding has been converted to yaml, the brcmnand controller driver has received a small fix, otherwise some more minor changes have also made their way in. * SPI NAND changes The SPI NAND subsystem has seen a great improvement, with the advent of DTR operations (DDR operations, which may be extended to the address cycles). The first vendor driver to benefit from these improvements is the Winbond driver. A new manufacturer driver is added SkyHigh, with a new constraint for the core, it is impossible to disable the on-die ECC engine. A Foresee device is also now supported.

SPI NOR changes for 6.14 Notable changes: - Add flash entries for Atmel AT25SF321, Spansion S28HL256T, S28HL02GT. - Add support for vcc-supply regulators and their DT bindings. - Drop mx25u25635f entry. The flash shares its ID with mx25u25645g and both parts have an SFDP table. Removing their entry lets them be driven by the generic SFDP-based driver.
