From f7a3be503f166a08259a983daa7df12b9e149c46 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 2 Feb 2016 14:43:14 +0200 Subject: [PATCH] ARM: davinci: dm355: 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.
