From 0b7ee71794b043de8a02d8887b69a57e4003106a Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Mon, 26 Mar 2012 10:29:23 +0530 Subject: SPEAr: Add PL080 DMA support for 3xx and 6xx Both SPEAr3xx and SPEAr6xx families have one instance of ARM PL080 DMA controller. This patch adds in support for that.
