Actually there are some differences, AT91 does not use a DMA, we use a specific IP(PDC) to transer the data...
PDC is still DMA ;) I guess AT91 uses the "old" PDC and not PDCA?
I don't know about any PDCA...so yes I guess we are using the old one...
Maybe we could share the same code we some #define in it?
Yes, it should be simple to add an additional #define in kconfig.
config SND_ATMEL_AC97C_PDC bool depends on ARCH_AT91
And then have some ifdefs/else around the DMA stuff, much like the atmel-mci driver does today.
I don't know which solution is the dest: ifdef or as Mark's one...
