[PATCH RFC 00/26] Migrate more OMAP DMA code to DMA engine

Nice to see this happening. These seem to work for me based on a quick
try on omap2+, but on omap1 the build fails:

arch/arm/mach-omap1/dma.c: In function ‘dma_write’:
arch/arm/mach-omap1/dma.c:186: error: ‘const struct omap_dma_reg’ has no member named ‘size’
