The main work would be to switch the DMA engine in MSM to using the DMA engine in drivers/dma. This is one thing we do to avoid the proliferation of DMA engine code in arch/arm/*, and we very early started to use that framework for U300 and Ux500 and I must say that it has payed off well for us, now we have much nicer interfaces and more review than any of the custom engines under arch/arm/*. It's some upfront work but I think it would benefit you if you could do this.
