From c2dde5f8f2095d7c623ff3565c1462e190272273 Mon Sep 17 00:00:00 2001 From: Matt Porter Date: Wed, 22 Aug 2012 21:09:34 -0400 Subject: dmaengine: add TI EDMA DMA engine driver Add a DMA engine driver for the TI EDMA controller. This driver is implemented as a wrapper around the existing DaVinci private DMA implementation. This approach allows for incremental conversion of each peripheral driver to the DMA engine API. The EDMA driver supports slave transfers but does not yet support cyclic transfers.
