From a4f86c55b9429b220d2c130f8b7ebb6e2ea6c727 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 2 Feb 2016 14:43:16 +0200 Subject: [PATCH] ARM: davinci: dm644x: 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.
