Could you please make something similar for SND_ATMEL_SOC_SSC_PDC? Also, I think that it should select ATMEL_SSC, to be able to use simple/graph-card with SSC.
Hmm. The Kconfig dependencies seems overly complicated, do you mind if I get rid of most of the entries in the process?
Unfortunately, it is just complicated enough. This is done to support all the possible configurations. Removing them will lead to linking errors.
After having that discussion back in March, I had a very quick look and didn't send a patch because I still had linking issues. It is not impossible but it required more time than I had.
Can you try patch below if it covers the configurations you mention? This uses Kconfig's m/y resolution instead of open-coded defaults.
Best Regards, Michał Mirosław
