Subject: [at91sam9g45] DMA driver for AC97 and MCI

I try to get sound and SD card working on at91sam9g45-ekes development board using linux-next tree. As far as I understand AT_HDMAC is the appropriate DMA driver for ARCH_AT91SAM9G45. I resolved dependencies with this patch, so I could activate it for my platform.

          Support the Atmel AHB DMA controller.  This can be integrated in

Should this driver be also used for sound driver and MCI?
