First patch adds the TI_EDMA option which people can forget to add and can result in failure without any informative errors of why DMA is not working. There was a discussion on avoiding Kconfig and putting this in the defconfig instead. Second patch adds comments to the EDMA code for the calculations in the A-sync case. From my experience, this code is not-so-obvious. Hopefully this makes the life of readers of the code a little better.
