Were you planning to send v2 of your series [2]? I see you made a mistake you were planning on fixing: https://lkml.org/lkml/2014/7/30/423 Brian > Best Regards, > > Boris > > [1]https://github.com/bbrezillon/linux-sunxi/tree/sunxi-nand-v4 > [2]https://lkml.org/lkml/2014/7/28/156 > > Changes since v3: > - removed nand core code modifications from the patch series (submitted > separately) > - added documentation to the code > - forced timeout (a default timeout is used when none is provided by the > caller) on controller operations > - fixed coding style issues > - removed unneeded irq field from the sunxi_nfc struct > - fixed several memory leaks > - reworked the NFC reset code (to avoid potential garbage config from the > bootloader) > - made use of ECC_EXCEPTION flag to prevent erased page from generating > ECC errors > - changed the OOB layout for HW ECC scheme > > Changes since v2: > - merge HW ECC implementation in base implementation patch > - fix timing config when interfacing with an ONFI compatible chip > > 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 (2): > mtd: nand: add sunxi NAND flash controller support > mtd: nand: add sunxi NFC dt bindings doc > > .../devicetree/bindings/mtd/sunxi-nand.txt | 45 + > drivers/mtd/nand/Kconfig | 6 + > drivers/mtd/nand/Makefile | 1 + > drivers/mtd/nand/sunxi_nand.c | 1362 ++++++++++++++++++++ > 4 files changed, 1414 insertions(+) > create mode 100644 Documentation/devicetree/bindings/mtd/sunxi-nand.txt > create mode 100644 drivers/mtd/nand/sunxi_nand.c > -- 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
