This patch will allow to use DMA again and it will avoid access to MCI register ATMCI_DMA. Even if the IP version is lower than v3xx and doesn't have the DMA configuration register, DMA transfers can be used with a different controller than the Atmel AHB DMA one. For instance, some AVR chips use the Synopsys DesignWare AHB DMA controller. Signed-off-by: Hein Tibosch Acked-by: Ludovic Desroches Signed-off-by: Chris Ball --- Reading git-diff-tree failed
