dma: ipu_idmac: reuse is_slave_direction helper

2013-01-12T13:07:22Z

The is_slave_direction helps to check if the transfer type is slave. Signed-off-by: Andy Shevchenko Reviewed-by: Viresh Kumar Cc: Guennadi Liakhovetski Signed-off-by: Vinod Koul

dma: ipu: Drop unused spinlock

2013-01-08T06:05:15Z

I was checking why this spinlock was never initialized, but it turns out it's not used anywhere, so we can drop it. Signed-off-by: Jean Delvare Cc: Vinod Koul Signed-off-by: Dan Williams

dma: ipu: rename mach/ipu.h to include/linux/dma/ipu-dma.h

2012-10-15T02:03:12Z

The header ipu.h really belongs to dma subsystem rather than imx platform. Rename it to ipu-dma.h and put it into include/linux/dma/.

dma: ipu: remove the use of ipu_platform_data

2012-07-01T13:57:43Z

The struct ipu_platform_data is used by platform code to pass MXC_IPU_IRQ_START to ipu-core driver. We can save it by having ipu-core driver call irq_alloc_descs to get the irq_base. Signed-off-by: Shawn Guo Acked-by: Vinod Koul Acked-by: Sascha Hauer Acked-by: Dong Aisheng

dmaengine: add context parameter to prep_slave_sg and prep_dma_cyclic

2012-03-21T13:50:23Z

Add context parameter to device_prep_slave_sg() and device_prep_dma_cyclic() interfaces to allow passing client/target specific information associated with the data transfer. Modify all affected DMA engine drivers. Signed-off-by: Alexandre Bounine Acked-by: Linus Walleij Acked-by: Felipe Balbi Signed-off-by: Vinod Koul

dmaengine: consolidate assignment of DMA cookies

2012-03-13T06:06:52Z

Everyone deals with assigning DMA cookies in the same way (it's part of the API so they should be), so lets consolidate the common code into a helper function to avoid this duplication.

dmaengine: add private header file

2012-03-13T06:06:44Z

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.
