From 2137d54d1643c1dcb1ff919f169b4542669a372e Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 2 Feb 2016 14:43:17 +0200 Subject: ARM: davinci: dm646x: Add dma_slave_map to edma Provide the dma_slave_map to edma which will allow us to move the drivers to the new, simpler dmaengine API and we can remove the DMA resources also for the devices.
