Layout drivers are used to describe the NVMEM storage format. The patchset also adds the support to read nvmem-cells via the devfs. This makes it possible to read the cells from the board code or shell without the need of referencing the cells within the DT. A long with the alignment and feature work I fixed a few issues like: honor the DT alias for a nvmem provider correctly. For the new features to work correctly the NVMEM core had to be partly (re-)synced with the one from Linux. This involved porting different DT helpers. Unfortunately this patchset doesn't add a NVMEM layout driver therefore a __dummy__.o is added within the Makefile. I decided to start from a fresh v1 because of the rework I've done. But for reference, the previous patchset can be found here: - https://lore.kernel.org/barebox/20240613131531.364894-1-m.felsch@pengutronix.de/ Regards, Marco Signed-off-by: Marco Felsch --- Marco Felsch (15): of: sync of_*_phandle_with_args with Linux of: base: add of_parse_phandle_with_optional_args() of: device: Export of_device_make_bus_id() nvmem: core: fix nvmem_register error path nvmem: core: sync with Linux nvmem: core: expose nvmem cells as cdev nvmem: core: allow single and dynamic device ids eeprom: at24: fix device name handling nvmem: core: create a header for internal sharing nvmem: core: add nvmem-layout support nvmem: core: add an index parameter to the cell nvmem: core: add per-cell post processing nvmem: core: add cell based fixup logic nvmem: core: provide own priv pointer in post process callback nvmem: core: drop global cell_post_process drivers/eeprom/at24.c | 18 +- drivers/nvmem/Kconfig | 7 + drivers/nvmem/Makefile | 3 + drivers/nvmem/core.c | 689 ++++++++++++++++++++++++++++++----------- drivers/nvmem/imx-ocotp-ele.c | 12 +- drivers/nvmem/internals.h | 53 ++++ drivers/nvmem/layouts.c | 173 +++++++++++ drivers/nvmem/layouts/Kconfig | 13 + drivers/nvmem/layouts/Makefile | 7 + drivers/nvmem/ocotp.c | 12 +- drivers/nvmem/regmap.c | 5 +- drivers/of/base.c | 280 +++++++++++------ drivers/of/device.c | 37 +++ drivers/of/platform.c | 36 +-- include/linux/nvmem-consumer.h | 17 +- include/linux/nvmem-provider.h | 148 ++++++++- include/of.h | 146 ++++++++- include/of_device.h | 3 + 18 files changed, 1293 insertions(+), 366 deletions(-) --- base-commit: 89bf1fcc998fc5fea0ce613d9930dd9ee39c0fb2 change-id: 20250701-v2025-06-0-topic-nvmem-c747b64106e2 Best regards, -- Marco Felsch
