ARM: imx: Add the secondary request into the structure for imx-sdma SDMA supports device to device (per_2_per) scripts to handle DMA transfering between two peripheral devices. The per_2_per script, however, needs two dma requests from two sides while the current structure only defined one request. So this patch just simply adds the secondary request so as to let SDMA and its user to add its implementation later. [ Both change in the SDMA driver and its users like Freescale ASRC ASoC driver should be taken along with this change in order to truly support per_2_per sciprts. However, we here make an expediency by adding this first so that we can add either side later since this patch won't break any function and meanwhile it can make merge window more smoothly: we don't need to apply the change inside dmaengine branch via ASoC tree any more. -- Nicolin ] Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com> Acked-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

dmaengine: imx-sdma: Add a new DMATYPE for Shared Peripheral ASRC Shared Peripheral ASRC, running on SPBA, needs to use shp sciprts for DMA transfer. So this patch just adds a new DMATYPE for it.

dma: imx-sdma: Add new dma type for ssi dual fifo script This patch adds a new DMA_TYPE for SSI dual FIFO script, included in SDMA firmware version 2. This script would allow SSI use dual fifo mode to transimit/receive data without occasional hardware underrun/overrun.

dma: imx-dma: Add oftree support Adding devicetree support for imx-dma driver. Use driver name for function 'imx_dma_is_general_purpose' because the devicename for devicetree initialized devices is different.

dma: imx-dma: remove cpu_is_xxx by using platform_device_id It changes the driver to use platform_device_id rather than cpu_is_xxx to determine the controller type, and updates the platform code accordingly. As the result, mach/hardware.h inclusion gets removed from the driver.
