NAND dma prefetch has been broken for awhile and seems to have only worked for sdma based devices.
This patchset fixes DMA prefetch to work on both edma and sdma devices Tested on: am335x general purpose evm am437x general purpose evm am37x general purpose evm This patchset depends on Roger Quadros recent v4 GPMC/NAND patchset https://github.com/rogerq/linux.git branch: for-v4.4/gpmc-v4 Franklin S Cooper Jr (5): mtd: nand: omap2: Support parsing dma channel information from DT mtd: nand: omap2: Start dma request before enabling prefetch mtd: nand: omap2: Fix high memory dma prefetch transfer ARM: dts: am437x/am33xx/omap3/dm816x: Add gpmc dma channel ARM: OMAP2+: Update gpmc and nand DT binding documentation .../bindings/memory-controllers/omap-gpmc.txt | 7 ++++++- .../devicetree/bindings/mtd/gpmc-nand.txt | 2 ++ arch/arm/boot/dts/am33xx.dtsi | 2 ++ arch/arm/boot/dts/am4372.dtsi | 2 ++ arch/arm/boot/dts/dm816x.dtsi | 2 ++ arch/arm/boot/dts/omap3.dtsi | 2 ++ drivers/mtd/nand/omap2.c | 24 ++++++++-------------- 7 files changed, 25 insertions(+), 16 deletions(-) -- 2.6.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
