Subject[PATCH 0/3] Pending dmaengine patches
Date
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).
