After the latest changes to atmel-mci, it could not be used with DMA on the AVR32 platform. This patch will allow to use DMA again and it will avoid access to MCI register ATMCI_DMA. v2: 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. v2: in atmci_configure_dma: check both pdata and pdata->dma_slave Signed-off-by: Hein Tibosch <redacted> Acked-by: Ludovic Desroches <redacted> --- drivers/mmc/host/atmel-mci.c | 26 +++++++++++++------------- 1 files changed, 13 insertions(+), 13 deletions(-)
Thanks, pushed to mmc-next for 3.7. (For the future, please put the patch changelog below the "---" instead of above it; that way it doesn't go into the git commit history.) - Chris. -- Chris Ball [off-list ref] <http://printf.net/> One Laptop Per Child
