Subject: [PATCH 0/5] mtd: nand: Fix support for NAND DMA Prefetch
Date: Mon, 12 Oct 2015 20:38:53 -0500 [thread overview]
Message-ID: <1444700338-27582-1-git-send-email-fcooper@ti.com> (raw)
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
