This patch series dedicated to make DMA working on Intel Medfield device with SPI DW and DW DMA. The previous version would be found here [1]. First two patches are bug fixes. Patch 5/9 is bugfix as well, though it's not marked as a fix to reduce a noise on stable kernels, where DMA wasn't working properly anyway. Last one is the removal of old DMA driver, since the only user of it in upstrem was SPI DW. NOTE: the patch series depends on not applied yet [2, 3]. Vinod, since the patch 9/9 removes the driver your are author of, please give your Ack. Reliminary answer, as I remember, was okay to remove. The driver was tested in loop back mode. It looks like there are not so many users of it right now, but I would really appreciate if anyone could test the driver on different hardware platforms (to be sure that I didn't break it). As a side effect the patch 8/9 fixes the memore leak in probe(). Mark, we discussed tha bug earlier in last year.
