dmaengine: omap-dma: Add support for DMA filter mapping to slave devices
Add support for providing device to filter_fn mapping so client drivers can switch to use the dma_request_chan() API. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
