2013-10-31ARM: 7857/1: dma: imx-sdma: setup dma maskPhilippe Retornaz
The dma mask is not configured in the current code. This was triggered by soc-dmaengine-pcm which allocate the dma buffers with the imx-sdma as device. This commit fix audio on imx31.

2013-10-31DMA-API: dma: edma.c: no need to explicitly initialize DMA masksRussell King
register_platform_device_full() can setup the DMA mask provided the appropriate member is set in struct platform_device_info. So lets make that be the case. This avoids a direct reference to the DMA masks by this driver. While here, add the dma_set_mask_and_coherent() call which the DMA API requires DMA-using drivers to call.

2013-10-31DMA-API: dma: dw_dmac.c: convert to use dma_coerce_mask_and_coherent()Russell King
This code sequence: if (!pdev->dev.dma_mask) { pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask; pdev->dev.coherent_dma_mask = DMA_BIT_MASK(32); } bypasses the architectures check on the DMA mask. It can be replaced with dma_coerce_mask_and_coherent(), avoiding the direct initialization of this mask. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2013-10-31DMA-API: dma: pl330: add dma_set_mask_and_coherent() callRussell King

2013-10-21dma: edma: Increase maximum SG limit to 20Joel Fernandes
davinci-pcm uses 16 as the no.of periods. With this, in EDMA we have to allocate atleast 17 slots: 1 slot for channel, and 16 slots the periods. Due to this, the MAX_NR_SG limitation causes problems, set it to 20 to make cyclic DMA work when davinci-pcm is converted to use DMA Engine. Also add a comment clarifying this.

2013-10-21dma: edma: Split out PaRAM set calculations into its own functionJoel Fernandes
PaRAM set calculation is abstracted into its own function to enable better reuse for other DMA cases such as cyclic. We adapt the Slave SG case to use the new function. This provides a much cleaner abstraction to the internals of the PaRAM set. However, any PaRAM attributes that are not common to all DMA types must be set separately such as setting of interrupts. This function takes care of the most-common attributes. Also added comments clarifying A-sync case calculations.
