I was prompted to look into this again as someone recently remarked: " cool, to bad spi does not work properly on allwinner..." Two and a half years ago, we were told this will all be handled with DMA. A year or so ago, we were told this will all be handled with DMA. A week or so ago, we were told this will all be handled with DMA. See the pattern? When DMA finally takes over, this fallback path is not mutually exclusive. Changes since V6: Rebased to make sure it applies on top of 4.9-rc. Also tested on actual hardware.
