dt-bindings: Updates Linus Walleij's mail address

2025-12-16T16:17:59Z

My name is stamped into maintainership for a big slew of DT bindings. Now that it is changing, switch it over to my kernel.org mail address, which will hopefully be stable for the rest of my life.

dt-bindings: mtd: fixed-partitions: Fix "compression" typo

dt-bindings: mtd: fixed-partition: Add binman compatibles

2024-04-15T10:06:03Z

Add two compatibles for binman entries, as a starting point for the schema. Note that, after discussion on v2, we decided to keep the existing meaning of label so as not to require changes to existing userspace software when moving to use binman nodes to specify the firmware layout. Note also that, after discussion on v6, we decided to use the same 'fixed-partition' schema for the binman features, so this version adds a new 'binman.yaml' file providing the new compatibles to the existing partition.yaml binding.

dt-bindings: mtd: fixed-partitions: Add alignment properties

2024-04-15T10:06:01Z

Add three properties for controlling alignment of partitions, aka 'entries' in fixed-partition. For now there is no explicit mention of hierarchy, so a 'section' is just the 'fixed-partitions' node. These new properties are inputs to the Binman packaging process, but are also needed if the firmware is repacked, to ensure that alignment constraints are not violated. Therefore they are provided as part of the schema.

Pull mtd updates from Miquel Raynal: "The main set of changes is related to Uwe's work converting platform remove callbacks to return void. Comes next (in number of changes) Kees' additional structures annotations to improve the sanitizers. The usual amount of cleanups apply. About the more substancial contribution, one main function of the partitions core could return an error which was not checked, this is now fixed. On the bindings side, fixed partitions can now have a compression property. Finally, an erroneous situation is now always avoided in the MAP RAM driver. CFI: - A several years old byte swap has been fixed. NAND: - The subsystem has, as usual, seen a bit of cleanup being done this cycle, typically return values of platform_get_irq() and devm_kasprintf(). There is also a better ECC check in the Arasan driver. This comes with smaller misc changes. - In the SPI-NAND world there is now support for Foresee F35SQA002G, Winbond W25N and XTX XT26 chips. SPI NOR: - For SPI NOR we cleaned the flash info entries in order to have them slimmer and self explanatory. In order to make the entries as slim as possible, we introduced sane default values so that the actual flash entries don't need to specify them. We now use a flexible macro to specify the flash ID instead of the previous INFOx() macros that had hardcoded ID lengths. Instead of: { "w25q512nwm", INFO(0xef8020, 0, 64 * 1024, 0) OTP_INFO(256, 3, 0x1000, 0x1000) }, We now use: .id = SNOR_ID(0xef, 0x80, 0x20), .name = "w25q512nwm", .otp = SNOR_OTP(256, 3, 0x1000, 0x1000), - We also removed some flash entries: the very old Catalyst SPI EEPROMs that were introduced once with the SPI-NOR subsystem, and a Fujitsu MRAM. Both should use the at25 EEPROM driver. The latter even has device tree bindings for the at25 driver. - We made sure that the conversion didn't introduce any unwanted changes by comparing the .rodata segment before and after the conversion. The patches landed in linux-next immediately after v6.6-rc2, we haven't seen any regressions yet. - Apart of the autumn cleaning we introduced a new flash entry, at25ff321a, and added block protection support for mt25qu512a" * tag 'mtd/for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: (91 commits) mtd: cfi_cmdset_0001: Byte swap OTP info mtd: rawnand: meson: check return value of devm_kasprintf() mtd: rawnand: intel: check return value of devm_kasprintf() mtd: rawnand: sh_flctl: Convert to module_platform_driver() mtd: spi-nor: micron-st: use SFDP table for mt25qu512a mtd: spi-nor: micron-st: enable lock/unlock for mt25qu512a mtd: rawnand: Remove unused of_gpio.h inclusion mtd: spinand: Add support for XTX XT26xxxDxxxxx mtd: spinand: winbond: add support for serial NAND flash mtd: rawnand: cadence: Annotate struct cdns_nand_chip with __counted_by mtd: rawnand: Annotate struct mtk_nfc_nand_chip with __counted_by mtd: spinand: add support for FORESEE F35SQA002G mtd: rawnand: rockchip: Use struct_size() mtd: rawnand: arasan: Include ECC syndrome along with in-band data while checking for ECC failure mtd: Use device_get_match_data() mtd: spi-nor: nxp-spifi: Convert to platform remove callback returning void mtd: spi-nor: hisi-sfc: Convert to platform remove callback returning void mtd: maps: sun_uflash: Convert to platform remove callback returning void mtd: maps: sa1100-flash: Convert to platform remove callback returning void mtd: maps: pxa2xx-flash: Convert to platform remove callback returning void ...

dt-bindings: nvmem: move deprecated cells binding to its own file

2023-10-21T17:19:06Z

Support for old NVMEM fixed cells was deprecated in favour of "fixed-layout". It's still part of the nvmem.yaml though and may be unknowingly used by new bindings added without much of analyze. To make it more difficult to accidentally support old syntax move its binding to separated file with "deprecated" in its name.
