Mika Westerberg 2389d674bf dmaengine/ep93xx_dma: add module.h include 
Due to module.h cleanup it is not anymore included implicitly. Drivers who
want to use it need to include it explicitly.

H Hartley Sweeten e2f5e5a71d dma/ep93xx_dma.c: local symbols should be static 
The symbol 'ep93xx_dma_prep_dma_memcpy' is only used in this driver
and should be marked static.

Mika Westerberg 5fa29a17fa dmaengine: add ep93xx DMA support 
The ep93xx DMA controller has 10 independent memory to peripheral (M2P)
channels, and 2 dedicated memory to memory (M2M) channels. M2M channels can
also be used by SPI and IDE to perform DMA transfers to/from their memory
mapped FIFOs.

This driver supports both M2P and M2M channels with DMA_SLAVE, DMA_CYCLIC and
DMA_MEMCPY (M2M only) capabilities.
