2012-03-13dmaengine: add private header fileRussell King - ARM Linux
Add a local private header file to contain definitions and declarations which should only be used by DMA engine drivers. We also fix linux/dmaengine.h to use LINUX_DMAENGINE_H to guard against multiple inclusion.

2012-03-13dmaengine: move last completed cookie into generic dma_chan structureRussell King - ARM Linux
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.

2012-03-09Revert "drivers/dma: linux/module.h included twice"Vinod Koul
This reverts commit 865d9438eb1f7670d2e88849f059db551b320887. The module.h incsuion twice has been updated tree wide hence this is not required to be merged. Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
2012-03-06dmaengine: Add support for multiple descriptors for imx-dma.Javier Martin
dmaengine specifies the possibility that several descriptors can be queued for transfer. It also indicates that tasklets must be used for DMA callbacks.

2012-02-28includecheck: delete any duplicate instances of module.hPaul Gortmaker
Different tree maintainers picked up independently generated trivial compile fixes based on linux-next testing, resulting in some cases where a file would have got more than one addition of module.h once everything was all merged together. Delete any duplicates so includecheck isn't complaining about anything related to module.h/export.h changes. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2012-01-30dma: imx-dma: start transfer in issue_pendingSascha Hauer
The DMA engine API requires that transfers are started in issue_pending instead of tx_submit. Fix this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> [corrected change log to DMA engine API insteadof DMA API] Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>

2011-07-07ARM i.MX dma: Fix burstsize settingsSascha Hauer
dmaengine expects the maxburst parameter in words, not bytes. The imxdma driver and its users do this wrong. Fix this. As a side note the imx-pcm-dma-mx2 driver was 'fixed' to work with imx-dma. This broke the driver with imx-sdma support which correctly takes the maxburst parameter in words. This patch puts the sdma based sound back to work.

2010-10-07dmaengine: Add Freescale i.MX1/21/27 DMA driverSascha Hauer
This driver is currently implemented as a user to the old i.MX DMA API. This allows us to convert each user of the old API to the dmaengine API one by one. Once this is done the old DMA driver can be merged into the i.MX dmaengine driver.
