Quick question:

In addition to cleaning up the enums in edma.h, are you also asking to 
pull the channel / base resources for ASP currently defined in asp.h 
into devices-da8xx.c as well?  Or should that be left alone? E.G., 
these defines look like they should go in devices-da8xx and come out 
of asp.h:

DAVINCI_DA8XX_MCASP0_REG_BASE
DAVINCI_DA830_MCASP1_REG_BASE
DAVINCI_DA8XX_DMA_MCASP0_AREVT
DAVINCI_DA8XX_DMA_MCASP0_AXEVT
DAVINCI_DA830_DMA_MCASP1_AREVT
DAVINCI_DA830_DMA_MCASP1_AXEVT

If moved, there are other #defines that should then be shuffled out of asp.h
to other files for other chips/platforms for completeness, E.G.

DAVINCI_DM646X_DMA_MCASP0_AXEVT0 should go to dm646x.c.

I'm not too keen on shuffling stuff around like that if I can't test it beyond
compiling.  Especially if it's not adding any functionality.  But, I will submit
it if it's necessary to get the SPI support in.

Thanks.
