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).
