one single FIFO. The WM9712 I worked with sends data in slot 12 which we have to sort out manually from the FIFO, so I think there is no way to work around the fiq handler using the DMA engine with AC97.
Slot 12 is used for GPIOs to allow them to be read/written without register accesses - I'd expect that data there will not be uncommon.
The devdma code is actually a copy of sound/arm/devdma.[ch]. It should probably be selected somehow instead of duplicated.
Yes, ideally. A simple Makefile change in sound/arm should do the trick. Other than this I'm happy with all the patches I've not specifically commented on.
