This patchset contains following changes:
-> SPI+DMA Enablements. omap_mcspi driver has been modified accordingly
-> Modifications to DMA driver.
UART+DMA integration requires a 'kickstart' during M2P. Hardware-specific support has been added in DMA driver (using dma_slot) and UART Tx Async API.
-> Modifications to soc/boards/dts to enable above changes
