[PATCH 1/2] dw_dmac: set CAP_PRIVATE capability for DW DMA controller

From: Hans-Christian Egtvedt
Date: Tue Mar 24 2009 - 07:35:28 EST


This patch adds the private capability for the DW DMA controller. This
allows the DMA controller to do other DMA transfers than
memory-to-memory. For example when the DMA controller is used by
peripherals to transfer data between memory and peripheral.
