Message-Id: <1237894506-11622-1-git-send-email-hans-christian.egtvedt@atmel.com> Date: Tue, 24 Mar 2009 12:35:05 +0100 From: Hans-Christian Egtvedt <hans-christian.egtvedt@...el.com> To: maciej.sosnowski@...el.com Cc: linux-kernel@...r.kernel.org, Hans-Christian Egtvedt <hans-christian.egtvedt@...el.com> Subject: [PATCH 1/2] dw_dmac: set CAP_PRIVATE capability for DW DMA controller 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.
