Pull MTD updates from Miquel Raynal: "Nothing stands out for this merge window, mostly minor fixes, such as module descriptions, the use of debug macros and Makefile improvements. Raw NAND changes; - The Freescale MXC driver has been converted to the newer '->exec_op()' interface - The meson driver now supports handling the boot ROM area with very specific ECC needs - Support for the iMX8QXP has been added to the GPMI driver - The lpx32xx driver now can get the DMA channels using DT entries - The Qcom binding has been improved to be more future proof by Rob - And then there is the usual load of misc and minor changes SPI-NAND changes: - The Macronix vendor driver has been improved to support an extended ID to avoid conflicting with older devices after an ID reuse issue SPI NOR changes: - Drop support for Xilinx S3AN flashes. These flashes are for the very old Xilinx Spartan 3 FPGAs and they need some awkward code in the core to support. Drop support for these flashes, along with the special handling we needed for them in the core like non-power-of-2 page size handling and the .setup() callback. - Fix regression for old w25q128 flashes without SFDP tables. Commit 83e824a4a595 ("mtd: spi-nor: Correct flags for Winbond w25q128") dropped support for such devices under the assumption that they aren't being used anymore. Users have now surfaced [0] so fix the regression by supporting both kind of devices. - Core cleanups including removal of SPI_NOR_NO_FR flag and simplification of spi_nor_get_flash_info()" Link: https://lore.kernel.org/r/CALxbwRo_-9CaJmt7r7ELgu+vOcgk=xZcGHobnKf=oT2=u4d4aA@mail.gmail.com/ [0] * tag 'mtd/for-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: (28 commits) mtd: rawnand: lpx32xx: Fix dma_request_chan() error checks mtd: spinand: macronix: Add support for serial NAND flash mtd: spinand: macronix: Add support for reading Device ID 2 mtd: rawnand: lpx32xx: Request DMA channels using DT entries dt-bindings: mtd: qcom,nandc: Define properties at top-level mtd: rawnand: intel: use 'time_left' variable with wait_for_completion_timeout() mtd: rawnand: mxc: use 'time_left' variable with wait_for_completion_timeout() mtd: rawnand: gpmi: add iMX8QXP support. mtd: rawnand: gpmi: add 'support_edo_timing' in gpmi_devdata mtd: cmdlinepart: Replace `dbg()` macro with `pr_debug()` mtd: add missing MODULE_DESCRIPTION() macros mtd: make mtd_test.c a separate module dt-bindings: mtd: gpmi-nand: Add 'fsl,imx8qxp-gpmi-nand' compatible string mtd: rawnand: cadence: remove unused struct 'ecc_info' mtd: rawnand: mxc: support software ECC mtd: rawnand: mxc: implement exec_op mtd: rawnand: mxc: separate page read from ecc calc mtd: spi-nor: winbond: fix w25q128 regression mtd: spi-nor: simplify spi_nor_get_flash_info() mtd: spi-nor: get rid of SPI_NOR_NO_FR ...

dt-bindings: mtd: qcom,nandc: Define properties at top-level

2024-07-17T08:39:38+00:00

Convention is DT schemas should define all properties at the top-level and not inside of if/then schemas. That minimizes the if/then schemas and is more future proof. There were 2 "if" schemas for "qcom,ipq806x-nand" and the "qcom,boot-partitions: true" unnecessary, so the conditional schemas can be simplified a bit.

dt-bindings: mtd: amlogic,meson-nand: support fields for boot ROM code

2024-05-27T11:52:07+00:00

Boot ROM code on Meson requires that some pages on NAND must be written in special mode: "short" ECC mode where each block is 384 bytes and scrambling mode is on. Such pages are located on the chip in the following way (for example): [ p0 ][ p1 ][ p2 ][ p3 ][ p4 ][ p5 ][ p6 ][ p7 ] ... [ pN ] ^ ^ ^ ^ pX is page number "X". "^" means "special" page used by boot ROM - e.g. every 2nd page in the range of [0, 7]. Step (2 in example is set by 'amlogic,boot-page-step' field. Last page in range (7 in example) is set by 'amlogic,boot-pages' field.

dt-bindings: Use full path to other schemas

2024-05-08T19:13:46+00:00

When referencing other schema, it is preferred to use an absolute path (/schemas/....), which allows also an seamless move of particular schema out of Linux kernel to dtschema.
