Subject: [PATCH 0/3] Pending dmaengine patches
Date: Thu, 18 Jul 2013 11:46:38 -0500 [thread overview]
Message-ID: <1374166001-31340-1-git-send-email-joelf@ti.com> (raw)
I've reworked Matt's dmaegine sg_limits series addressing review comments at [1].
Currently MMC on AM33xx requires EDMA which was posted and accepted, following
it is a series that are fixes that have to go in for it to work correctly.
Without this series, DMA fails on MMC resulting in I/O errors.
A subsequent MMC DT patch for AM33xx is also on hold [2] for the same reason.
Tested on AM335x (Beaglebone Rev A5A).
