Changes since v3 at [4]: - remove partition table and some used props from dt-bindings Changes since v2 at [3]: - remove some hardcode time value, like twb - use dev wait R/B instead of nand_soft_waitrdy - implement nfc ecc init by ecc helper - rework nfc buffer init to register the maximun buffer when several chips - free nfc buffer when error and cleanup - add variable to teack all the already assigned CS lines - fix mtd->name use the first cs line only - remove dt "nand-enable-scrambler" and use NAND_NEED_SCRAMBLING instead. - move setuping ECC fileds after the identification phase - use nand_scan() and attach_chip() - check one event to return IRQ_NONE - delete cast when of_device_get_match_data - use nand_controller_init() helper - remove nfc driver complains when calling devm_ioremap_resource - clear irqs before setting up irq handler Changes since v1 at [1]: - adopt property amlogic,nand-enable-scrambler - thanks Martin - drop nand pins in DT - convert clk access to emmc clkc model - fix regiser field definition alignment - drop nand-user-mode - parse cs id from DT - rework n2m, m2n function - explain why insert two "IDLE" command - implement exec_op() - drop meson_nfc_get_nand_chip_dts() - release resource once error occur in meson_nfc_nand_chips_init(), - call nand_cleanup(nand) once mtd_device_register fail Items not addressed ( or confirmed ) in this version: - convert to ECC conf helper() - convert to dma coherent API - how to construct mtd->name [1] https://lkml.kernel.org/r/20180613161314.14894-1-yixun.lan@amlogic.com [2] https://lkml.kernel.org/r/20180712211244.11428-1-yixun.lan@amlogic.com [3] https://lkml.kernel.org/r/20180719094612.5833-1-yixun.lan@amlogic.com [4] https://lkml.kernel.org/r/1536317831-58056-1-git-send-email-jianxin.pan@amlogic.com/ Liang Yang (2): dt-bindings: nand: meson: add Amlogic NAND controller driver mtd: rawnand: meson: add support for Amlogic NAND flash controller .../devicetree/bindings/mtd/amlogic,meson-nand.txt | 60 + drivers/mtd/nand/raw/Kconfig | 10 + drivers/mtd/nand/raw/Makefile | 1 + drivers/mtd/nand/raw/meson_nand.c | 1372 ++++++++++++++++++++ 4 files changed, 1443 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/amlogic,meson-nand.txt create mode 100644 drivers/mtd/nand/raw/meson_nand.c
