Hello, This series adds support for the sunxi NAND Flash Controller (NFC). This controller supports up to 8 NAND chip connected. I'm still in the early stages drivers development and some key features are missing, but it's usable (I tested it on the cubietruck board). Here's what's missing: - DMA support - HW randomization support - other improvements ? This series depends on Emilio's patch series implementing mod0 clks (http://lists.infradead.org/pipermail/linux-arm-kernel/2013-July/185478.html) + an other patch not yet posted (http://git.elopez.com.ar/linux/commits/5b4eb3ac406b9c98965714d40e8dd6da943d1ab0) Best Regards, Boris Changes since v1: - add HW ECC support - rework NAND timings retrieval (use ONFI timing mode instead of raw timings) - add nand-ecc-level property to specify NAND ECC requirements from DT Boris BREZILLON (14): mtd: nand: retrieve ECC requirements from Hynix READ ID byte 4 of: mtd: add NAND ECC level requirements retrieval of: mtd: add documentation for nand-ecc-level property mtd: nand: define struct nand_timings mtd: nand: add ONFI timing mode to nand_timings converter of: mtd: add NAND timing mode retrieval support of: mtd: add documentation for the ONFI NAND timing mode property mtd: nand: add sunxi NAND flash controller support mtd: nand: add sunxi NFC dt bindings doc ARM: dt/sunxi: add NFC node to Allwinner A20 SoC ARM: dt/sunxi: add NFC pinctrl pin definitions ARM: sunxi/dt: enable NAND on cubietruck board mtd: nand: add sunxi HW ECC support ARM: sunxi/dt: enable HW ECC on cubietruck board Documentation/devicetree/bindings/mtd/nand.txt | 8 + .../devicetree/bindings/mtd/sunxi-nand.txt | 46 + arch/arm/boot/dts/sun7i-a20-cubietruck.dts | 31 + arch/arm/boot/dts/sun7i-a20.dtsi | 35 + drivers/mtd/nand/Kconfig | 6 + drivers/mtd/nand/Makefile | 3 +- drivers/mtd/nand/nand_base.c | 37 + drivers/mtd/nand/nand_timings.c | 248 +++++ drivers/mtd/nand/sunxi_nand.c | 997 ++++++++++++++++++++ drivers/of/of_mtd.c | 44 + include/linux/mtd/nand.h | 53 ++ include/linux/of_mtd.h | 15 + 12 files changed, 1522 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/mtd/sunxi-nand.txt create mode 100644 drivers/mtd/nand/nand_timings.c create mode 100644 drivers/mtd/nand/sunxi_nand.c -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
