Yes, it should be possible to share the AC97C driver between AT91 and
AVR32. Although this AC97C driver uses the DesignWare DMAC controller
(drivers/dma/dw_dmac.c).
I do not remember which DMA interface AT91 devices uses.
Should the driver go into sound/drivers then? And renamed to
atmel-ac97c.{c,h} for example.
