* dmaengine: intel-mid-dma: remove the driverAndy Shevchenko2015-03-171-299/+0
| | | | | | | | | | | | Since the last and the only user of this driver is converted to use dw_dmac we can remove driver from the tree. Moreover, besides the driver is unmaintained a long time, it serves for the DesignWare DMA IP, for which we have already driver in the tree.

* dmaengine: move last completed cookie into generic dma_chan structureRussell King - ARM Linux2012-03-131-2/+0
| | | | | | | | | | | | | | | Every DMA engine implementation declares a last completed dma cookie in their private dma channel structures. This is pointless, and forces driver specific code. Move this out into the common dma_chan structure.

* intel_mid_dma: Add sg list support to DMA driverRamesh Babu K V2010-10-071-4/+26
| | | | | | | | | | | | For a very high speed DMA various periphral devices need scatter-gather list support. The DMA hardware support link list items. This list can be circular also (adding new flag DMA_PREP_CIRCULAR_LIST) Right now this flag is in driver header and should be moved to dmaengine header file eventually Signed-off-by: Ramesh Babu K V <ramesh.b.k.v@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* intel_mid: Add Mrst & Mfld DMA DriversVinod Koul2010-07-271-0/+260
This patch add DMA drivers for DMA controllers in Langwell chipset of Intel(R) Moorestown platform and DMA controllers in Penwell of Intel(R) Medfield platfrom This patch adds support for Moorestown DMAC1 and DMAC2 controllers. It also add support for Medfiled GP DMA and DMAC1 controllers. These controllers supports memory to peripheral and peripheral to memory transfers. It support only single block transfers. This driver is based on Kernel DMA engine Anyone who wishes to use this controller should use DMA engine APIs This controller exposes DMA_SLAVE capabilities and notifies the client drivers of DMA transaction completion Config option required to be enabled CONFIG_INTEL_MID_DMAC=y Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
