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 Test on: am335x gp evm am437x gp evm am37x gp 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/omap/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 ++ arch/arm/boot/dts/omap4.dtsi | 2 ++ arch/arm/boot/dts/omap5.dtsi | 2 ++ drivers/mtd/nand/omap2.c | 27 +++++++++------------- 9 files changed, 31 insertions(+), 17 deletions(-) -- 2.6.1 -- 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
