This patchset supports: - the command sequencer feature, a hardware accelerator for read/write within a page - the manual mode feature, useful for debug purpose - a maximum 8k page size - following ECC strength and step size - nand-ecc-strength = <8>, nand-ecc-step-size = <512> (BCH8) - nand-ecc-strength = <4>, nand-ecc-step-size = <512> (BCH4) - nand-ecc-strength = <1>, nand-ecc-step-size = <512> (Extended ecc based on HAMMING) This patchset has been tested on Micron MT29F8G08ABACAH4 (8-bit SLC NAND) and MT29F8G16ABACAH4 (16-bit SLC NAND) Changes v4: - rebase on nand/next - replace "manual mode" by "polling mode" Changes v3: - modify clocks property description - add NAND reg property description - stm32_fmc2_nfc inherits from nand_controller structure - rewrite stm32_fmc2_read_data/stm32_fmc2_write_data functions to handle aligned and not aligned buffers - replace uint8_t by u8 - use of NAND_ROW_ADDR_3 option Changes v2: - separate the controller structure and the NAND chip structure - remove timings description from the device tree - fix typo issues - fix kbuildrobot issues Christophe Kerello (3): dt-bindings: mtd: stm32_fmc2: add STM32 FMC2 NAND controller documentation mtd: rawnand: stm32_fmc2: add STM32 FMC2 NAND flash controller driver mtd: rawnand: stm32_fmc2: add polling mode .../devicetree/bindings/mtd/stm32-fmc2-nand.txt | 61 + drivers/mtd/nand/raw/Kconfig | 9 + drivers/mtd/nand/raw/Makefile | 1 + drivers/mtd/nand/raw/stm32_fmc2_nand.c | 2073 ++++++++++++++++++++ 4 files changed, 2144 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/stm32-fmc2-nand.txt create mode 100644 drivers/mtd/nand/raw/stm32_fmc2_nand.c -- 1.9.1
