Subject: [PATCH v3 0/6] mtd: nand: Fix support for NAND DMA prefetch
Date: Wed, 9 Mar 2016 22:07:35 -0600 [thread overview]
Message-ID: <1457582861-20619-1-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
Test on:
am335x gp evm
am437x gp evm
am37x gp evm
This rev is pretty much the same as v2 which was blocked due to
dependencies to Roger's update GPMC/NAND rework.
This updated rev removes this dependency.
Also it fixes an issue that was introduced when the eDMA driver was
recently updated.
