It is based on top of v3.19 and was tested on the Marvell Berlin BG2Q DMP board. The support is added into the existing pxa3xx nand controller. Some additions were done in order to get this controller working: - Support for a non mandatory ECC clock has been added. - The Berlin nand controller needs to poll the status register. - Sequences of commands are quite different in order to perform write operation. Changes were done in order to avoid impacting other controllers using this driver, but I'd like people actually using the pxa3xx nand driver to test theses patches to ensure no harm was done. A specific Berlin nand cmd function has been added to deal with most of the Berlin specific code. Because of a bug in the Berlin clock driver, this series requires the fix provided by Jisheng Zhang, which is already in v3.19-rc6 (b71e8ecd57c8aae5b1815782c47b74ffe3efc09a). Thanks! Antoine Changes since v1: - Added a fallback to NULL when looking for the 'nfc' clock - Added the clocks in the bindings documentation - Reworked the DT - Removed non needed RNDOUT command - Used the standard RESET command - Fixed the flash type matching order - Remove all non tested flash types (only one left) - Added a check to explicitly not support nand chips with small pages - Remove useless checks for clocks in the probing function - Various clean up Antoine Tenart (10): mtd: pxa3xx_nand: initialiaze pxa3xx_flash_ids to 0 mtd: pxa3xx_nand: add a non mandatory ECC clock Documentation: bindings: document the clocks for pxa3xx-nand mtd: pxa3xx_nand: set NDCR_PG_PER_BLK if page per block is 128 mtd: pxa3xx_nand: add a default chunk size mtd: pxa3xx_nand: add support for the Marvell Berlin nand controller Documentation: bindings: add the Berlin nand controller compatible mtd: nand: let Marvell Berlin SoCs select the pxa3xx driver ARM: berlin: add BG2Q node for the nand ARM: berlin: enable flash on the BG2Q DMP .../devicetree/bindings/mtd/pxa3xx-nand.txt | 5 + arch/arm/boot/dts/berlin2q-marvell-dmp.dts | 25 ++ arch/arm/boot/dts/berlin2q.dtsi | 13 + drivers/mtd/nand/Kconfig | 2 +- drivers/mtd/nand/pxa3xx_nand.c | 268 ++++++++++++++++++--- 5 files changed, 276 insertions(+), 37 deletions(-) -- 2.3.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
