Hello, Here are a couple of fixes for the rcar-dmac driver. They're based on the next branch of the dmaengine tree. The first four patches fix driver bugs, while the last two work around two hardware issues. Patch 5 works around a documented errata, while patch 6 handles a data corruption issue that was noticed during test but not yet confirmed to be a hardware bug by Renesas. When more information about the issue will be available a better fix could possibly be developed. The patches are available at git://linuxtv.org/pinchartl/fbdev.git dma/upstream Vinod, is there still time for a v3.20 pull request ?
