Maybe you remember, those modifications where part of the famous AT91 board/device series that was postponed to 3.4 due to a flood of issues... So now, I would like to know if it is possible to resolve this problem by queuing the DMA related patches that we have already in at91/device-board branch to mainline before 3.3-final? The patches that I am talking about are: bdad0b9 ARM: at91/dma: remove platform data from DMA controller and 2756bf5 ARM: at91/dma: DMA controller registering with DT support I do think it is pretty silly to try to resolve this issue by not taking those two little patches and modifying source code to workaround this issue. If we do this, we will get conflicts and need to rework the already queued 3.4 material. Do you want me to prepare a new at91-fixes branch with those two patches or you can take them yourself? Thanks for your help, best regards, -- Nicolas Ferre
