This patch set introduces the dmaengine driver for the MSM 8x74 Bus Access
Manager (BAM) DMA controller.  A number of the on-chip devices have their own
BAM DMA controller and use it to move data between system memory and peripherals
or between two peripherals.

The initial version of this driver will only support slave DMA operations
between system memory and peripherals.
