From 1c5b0538c719f52cface39f699fb5d39a50149d6 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 3 Mar 2011 15:47:26 +0530 Subject: [PATCH] avr32: at32ap700x: Specify DMA Flow Controller, Src and Dst msize Now that the dw_dmac DMA driver supports configurable Flow Controller, source and destination burst or msize, we need to specify which ones to use. Msize or burst size was previously hardcoded to 1, Flow controller was DMA for both M2P & P2M transfers.
