I will merge this branch into mtd/next very soon but here is a PR for you as well if needed. Thanks, Miquèl The following changes since commit e783362eb54cd99b2cac8b3a9aeac942e6f6ac07: Linux 5.17-rc1 (2022-01-23 10:12:53 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux.git tags/mtd/spi-mem-ecc-for-5.18 for you to fetch changes up to 00360ebae483e603d55ec9a7231b787cb80ffe13: spi: mxic: Add support for pipelined ECC operations (2022-02-10 09:32:30 +0100) ---------------------------------------------------------------- Topic branch bringing-in changes related to the support of ECC engines that can be used by SPI controllers to manage SPI NANDs as well as possibly by parallel NAND controllers. In particular, it brings support for Macronix ECC engine that can be used with Macronix SPI controller. The changes touch the NAND core, the NAND ECC core, the spi-mem layer, a SPI controller driver and add a new NAND ECC driver, as well as a number of binding updates. Binding changes: * Vendor prefixes: Clarify Macronix prefix * SPI NAND: Convert spi-nand description file to yaml * Raw NAND chip: Create a NAND chip description * Raw NAND controller: - Harmonize the property types - Fix a comment in the examples - Fix the reg property description * Describe Macronix NAND ECC engine * Macronix SPI controller: - Document the nand-ecc-engine property - Convert to yaml - The interrupt property is not mandatory NAND core changes: * ECC: - Add infrastructure to support hardware engines - Add a new helper to retrieve the ECC context - Provide a helper to retrieve a pilelined engine device NAND-ECC changes: * Macronix ECC engine: - Add Macronix external ECC engine support - Support SPI pipelined mode SPI-NAND core changes: * Delay a little bit the dirmap creation * Create direct mapping descriptors for ECC operations SPI-NAND driver changes: * macronix: Use random program load SPI changes: * Macronix SPI controller: - Fix the transmit path - Create a helper to configure the controller before an operation - Create a helper to ease the start of an operation - Add support for direct mapping - Add support for pipelined ECC operations * spi-mem: - Introduce a capability structure - Check the controller extra capabilities - cadence-quadspi/mxic: Provide capability structures - Kill the spi_mem_dtr_supports_op() helper - Add an ecc parameter to the spi_mem_op structure ---------------------------------------------------------------- Mason Yang (1): mtd: spinand: macronix: Use random program load Miquel Raynal (28): dt-bindings: mtd: nand-controller: Fix the reg property description dt-bindings: mtd: nand-controller: Fix a comment in the examples dt-bindings: mtd: nand-controller: Harmonize the property types dt-bindings: mtd: nand-chip: Create a NAND chip description dt-bindings: mtd: spi-nand: Convert spi-nand description file to yaml dt-bindings: vendor-prefixes: Clarify Macronix prefix dt-bindings: spi: mxic: The interrupt property is not mandatory dt-bindings: spi: mxic: Convert to yaml dt-bindings: spi: mxic: Document the nand-ecc-engine property dt-bindings: mtd: Describe Macronix NAND ECC engine mtd: nand: ecc: Add infrastructure to support hardware engines mtd: nand: Add a new helper to retrieve the ECC context mtd: nand: mxic-ecc: Add Macronix external ECC engine support mtd: nand: ecc: Provide a helper to retrieve a pilelined engine device mtd: nand: mxic-ecc: Support SPI pipelined mode spi: spi-mem: Introduce a capability structure spi: spi-mem: Check the controller extra capabilities spi: cadence-quadspi: Provide a capability structure spi: mxic: Provide a capability structure spi: spi-mem: Kill the spi_mem_dtr_supports_op() helper spi: spi-mem: Add an ecc parameter to the spi_mem_op structure mtd: spinand: Delay a little bit the dirmap creation mtd: spinand: Create direct mapping descriptors for ECC operations spi: mxic: Fix the transmit path spi: mxic: Create a helper to configure the controller before an operation spi: mxic: Create a helper to ease the start of an operation spi: mxic: Add support for direct mapping spi: mxic: Add support for pipelined ECC operations Documentation/devicetree/bindings/mtd/mxicy,nand-ecc-engine.yaml | 77 +++ Documentation/devicetree/bindings/mtd/nand-chip.yaml | 70 +++ Documentation/devicetree/bindings/mtd/nand-controller.yaml | 72 +-- Documentation/devicetree/bindings/mtd/spi-nand.txt | 5 - Documentation/devicetree/bindings/mtd/spi-nand.yaml | 27 + Documentation/devicetree/bindings/spi/mxicy,mx25f0a-spi.yaml | 65 +++ Documentation/devicetree/bindings/spi/spi-mxic.txt | 34 -- Documentation/devicetree/bindings/vendor-prefixes.yaml | 3 + drivers/mtd/nand/Kconfig | 6 + drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/core.c | 10 +- drivers/mtd/nand/ecc-mxic.c | 879 ++++++++++++++++++++++++++++++++ drivers/mtd/nand/ecc.c | 119 +++++ drivers/mtd/nand/spi/core.c | 51 +- drivers/mtd/nand/spi/macronix.c | 2 +- drivers/spi/Kconfig | 1 + drivers/spi/spi-cadence-quadspi.c | 10 +- drivers/spi/spi-mem.c | 32 +- drivers/spi/spi-mxic.c | 340 +++++++++--- include/linux/mtd/nand-ecc-mxic.h | 49 ++ include/linux/mtd/nand.h | 49 ++ include/linux/mtd/spinand.h | 2 + include/linux/spi/spi-mem.h | 26 +- include/linux/spi/spi.h | 3 + 24 files changed, 1731 insertions(+), 202 deletions(-) create mode 100644 Documentation/devicetree/bindings/mtd/mxicy,nand-ecc-engine.yaml create mode 100644 Documentation/devicetree/bindings/mtd/nand-chip.yaml delete mode 100644 Documentation/devicetree/bindings/mtd/spi-nand.txt create mode 100644 Documentation/devicetree/bindings/mtd/spi-nand.yaml create mode 100644 Documentation/devicetree/bindings/spi/mxicy,mx25f0a-spi.yaml delete mode 100644 Documentation/devicetree/bindings/spi/spi-mxic.txt create mode 100644 drivers/mtd/nand/ecc-mxic.c create mode 100644 include/linux/mtd/nand-ecc-mxic.h
