[PATCH v2 0/5] mtd: nand: Fix support for NAND DMA prefetch

From: Franklin S Cooper Jr
Date: Thu Oct 15 2015 - 13:38:02 EST


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
